-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#

-'configure' configures libffi 3.5.2 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print 'checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for '--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or '..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, 'make install' will install all the files in
-'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than '$ac_default_prefix' using '--prefix',
-for instance '--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR        program executables [EPREFIX/libexec]

-  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
-  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
-  --libdir=DIR            object code libraries [EPREFIX/lib]
-  --includedir=DIR        C header files [PREFIX/include]
-  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
-  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
-  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
-  --infodir=DIR           info documentation [DATAROOTDIR/info]
-  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
-  --mandir=DIR            man documentation [DATAROOTDIR/man]
-  --docdir=DIR            documentation root [DATAROOTDIR/doc/libffi]
-  --htmldir=DIR           html documentation [DOCDIR]

+\`configure' configures libffi 3.6.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

   This is a version (aka dlmalloc) of malloc/free/realloc written by
   Doug Lea and released to the public domain, as explained at
-  http://creativecommons.org/licenses/publicdomain.  Send questions,
-  comments, complaints, performance data, etc to dl@cs.oswego.edu
-
-* Version 2.8.3 Thu Sep 22 11:16:15 2005  Doug Lea  (dl at gee)
-
-   Note: There may be an updated version of this malloc obtainable at
-           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
-         Check before installing!
-
-* Quickstart
-
-  This library is all in one file to simplify the most common usage:
-  ftp it, compile it (-O3), and link it into another program. All of
-  the compile-time options default to reasonable values for use on
-  most platforms.  You might later want to step through various
-  compile-time and dynamic tuning options.
-
-  For convenience, an include file for code using this malloc is at:
-     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
-  You don't really need this .h file unless you call functions not
-  defined in your system include files.  The .h file contains only the
-  excerpts from this file needed for using this malloc on ANSI C/C++
-  systems, so long as you haven't changed compile-time options about
-  naming and tuning parameters.  If you do, then you can create your
-  own malloc.h that does include all settings by cutting at the point
-  indicated below. Note that you may already by default be using a C
-  library containing a malloc that is based on some version of this
-  malloc (for example in linux). You might still want to use the one
-  in this file to customize settings or to avoid overheads associated
-  with library versions.
-
-* Vital statistics:
-
-  Supported pointer/size_t representation:       4 or 8 bytes
-       size_t MUST be an unsigned type of the same width as
-       pointers. (If you are using an ancient system that declares
-       size_t as a signed type, or need it to be a different width
-       than pointers, you can use a previous release of this malloc
-       (e.g. 2.7.2) supporting these.)
-
-  Alignment:                                     8 bytes (default)
-       This suffices for nearly all current machines and C compilers.
-       However, you can define MALLOC_ALIGNMENT to be wider than this
-       if necessary (up to 128bytes), at the expense of using more space.
-
-  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
-                                          8 or 16 bytes (if 8byte sizes)
-       Each malloced chunk has a hidden word of overhead holding size
-       and status information, and additional cross-check word
-       if FOOTERS is defined.
-
-  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
-                          8-byte ptrs:  32 bytes    (including overhead)
-
-       Even a request for zero bytes (i.e., malloc(0)) returns a
-       pointer to something of the minimum allocatable size.
-       The maximum overhead wastage (i.e., number of extra bytes
-       allocated than were requested in malloc) is less than or equal
-       to the minimum size, except for requests >= mmap_threshold that
-       are serviced via mmap(), where the worst case wastage is about
-       32 bytes plus the remainder from a system page (the minimal
-       mmap unit); typically 4096 or 8192 bytes.
-
-  Security: static-safe; optionally more or less
-       The "security" of malloc refers to the ability of malicious
-       code to accentuate the effects of errors (for example, freeing
-       space that is not currently malloc'ed or overwriting past the
-       ends of chunks) in code that calls malloc.  This malloc
-       guarantees not to modify any memory locations below the base of
-       heap, i.e., static variables, even in the presence of usage
-       errors.  The routines additionally detect most improper frees
-       and reallocs.  All this holds as long as the static bookkeeping
-       for malloc itself is not corrupted by some other means.  This
-       is only one aspect of security -- these checks do not, and
-       cannot, detect all possible programming errors.
-
-       If FOOTERS is defined nonzero, then each allocated chunk
-       carries an additional check word to verify that it was malloced
-       from its space.  These check words are the same within each
-       execution of a program using malloc, but differ across
-       executions, so externally crafted fake chunks cannot be
-       freed. This improves security by rejecting frees/reallocs that
-       could corrupt heap memory, in addition to the checks preventing
-       writes to statics that are always on.  This may further improve
-       security at the expense of time and space overhead.  (Note that
-       FOOTERS may also be worth using with MSPACES.)
-
-       By default detected errors cause the program to abort (calling
-       "abort()"). You can override this to instead proceed past
-       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
-       has no effect, and a malloc that encounters a bad address
-       caused by user overwrites will ignore the bad address by
-       dropping pointers and indices to all known memory. This may
-       be appropriate for programs that should continue if at all
-       possible in the face of programming errors, although they may
-       run out of memory because dropped memory is never reclaimed.
-
-       If you don't like either of these options, you can define
-       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
-       else. And if if you are sure that your program using malloc has
-       no errors or vulnerabilities, you can define INSECURE to 1,
-       which might (or might not) provide a small performance improvement.
-
-  Thread-safety: NOT thread-safe unless USE_LOCKS defined
-       When USE_LOCKS is defined, each public call to malloc, free,
-       etc is surrounded with either a pthread mutex or a win32
-       spinlock (depending on WIN32). This is not especially fast, and
-       can be a major bottleneck.  It is designed only to provide
-       minimal protection in concurrent environments, and to provide a
-       basis for extensions.  If you are using malloc in a concurrent
-       program, consider instead using ptmalloc, which is derived from
-       a version of this malloc. (See http://www.malloc.de).
-
-  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
-       This malloc can use unix sbrk or any emulation (invoked using
-       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
-       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
-       memory.  On most unix systems, it tends to work best if both
-       MORECORE and MMAP are enabled.  On Win32, it uses emulations
-       based on VirtualAlloc. It also uses common C library functions
-       like memset.
-
-  Compliance: I believe it is compliant with the Single Unix Specification
-       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
-       others as well.
-
-* Overview of algorithms
-
-  This is not the fastest, most space-conserving, most portable, or
-  most tunable malloc ever written. However it is among the fastest
-  while also being among the most space-conserving, portable and
-  tunable.  Consistent balance across these factors results in a good
-  general-purpose allocator for malloc-intensive programs.
-
-  In most ways, this malloc is a best-fit allocator. Generally, it
-  chooses the best-fitting existing chunk for a request, with ties
-  broken in approximately least-recently-used order. (This strategy
-  normally maintains low fragmentation.) However, for requests less
-  than 256bytes, it deviates from best-fit when there is not an
-  exactly fitting available chunk by preferring to use space adjacent
-  to that used for the previous small request, as well as by breaking
-  ties in approximately most-recently-used order. (These enhance
-  locality of series of small allocations.)  And for very large requests
-  (>= 256Kb by default), it relies on system memory mapping
-  facilities, if supported.  (This helps avoid carrying around and
-  possibly fragmenting memory used only for large chunks.)
-
-  All operations (except malloc_stats and mallinfo) have execution
-  times that are bounded by a constant factor of the number of bits in
-  a size_t, not counting any clearing in calloc or copying in realloc,
-  or actions surrounding MORECORE and MMAP that have times
-  proportional to the number of non-contiguous regions returned by
-  system allocation routines, which is often just 1.
-
-  The implementation is not very modular and seriously overuses
-  macros. Perhaps someday all C compilers will do as good a job
-  inlining modular code as can now be done by brute-force expansion,
-  but now, enough of them seem not to.
-
-  Some compilers issue a lot of warnings about code that is
-  dead/unreachable only on some platforms, and also about intentional
-  uses of negation on unsigned types. All known cases of each can be
-  ignored.
-
-  For a longer but out of date high-level description, see
-     http://gee.cs.oswego.edu/dl/html/malloc.html
-
-* MSPACES
-  If MSPACES is defined, then in addition to malloc, free, etc.,
-  this file also defines mspace_malloc, mspace_free, etc. These
-  are versions of malloc routines that take an "mspace" argument
-  obtained using create_mspace, to control all internal bookkeeping.
-  If ONLY_MSPACES is defined, only these versions are compiled.
-  So if you would like to use this allocator for only some allocations,
-  and your system malloc for others, you can compile with
-  ONLY_MSPACES and then do something like...
-    static mspace mymspace = create_mspace(0,0); // for example
-    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
-
-  (Note: If you only need one instance of an mspace, you can instead
-  use "USE_DL_PREFIX" to relabel the global malloc.)
-
-  You can similarly create thread-local allocators by storing
-  mspaces as thread-locals. For example:
-    static __thread mspace tlms = 0;
-    void*  tlmalloc(size_t bytes) {
-      if (tlms == 0) tlms = create_mspace(0, 0);
-      return mspace_malloc(tlms, bytes);
-    }
-    void  tlfree(void* mem) { mspace_free(tlms, mem); }
-
-  Unless FOOTERS is defined, each mspace is completely independent.
-  You cannot allocate from one and free to another (although
-  conformance is only weakly checked, so usage errors are not always
-  caught). If FOOTERS is defined, then each chunk carries around a tag
-  indicating its originating mspace, and frees are directed to their
-  originating spaces.
-
- -------------------------  Compile-time options ---------------------------
-
-Be careful in setting #define values for numerical constants of type
-size_t. On some systems, literal values are not automatically extended
-to size_t precision unless they are explicitly casted.
-
-WIN32                    default: defined if _WIN32 defined
-  Defining WIN32 sets up defaults for MS environment and compilers.
-  Otherwise defaults are for unix.
-
-MALLOC_ALIGNMENT         default: (size_t)8
-  Controls the minimum alignment for malloc'ed chunks.  It must be a
-  power of two and at least 8, even on machines for which smaller
-  alignments would suffice. It may be defined as larger than this
-  though. Note however that code and data structures are optimized for
-  the case of 8-byte alignment.
-
-MSPACES                  default: 0 (false)
-  If true, compile in support for independent allocation spaces.
-  This is only supported if HAVE_MMAP is true.
-
-ONLY_MSPACES             default: 0 (false)
-  If true, only compile in mspace versions, not regular versions.
-
-USE_LOCKS                default: 0 (false)
-  Causes each call to each public routine to be surrounded with
-  pthread or WIN32 mutex lock/unlock. (If set true, this can be
-  overridden on a per-mspace basis for mspace versions.)
-
-FOOTERS                  default: 0
-  If true, provide extra checking and dispatching by placing
-  information in the footers of allocated chunks. This adds
-  space and time overhead.
-
-INSECURE                 default: 0
-  If true, omit checks for usage errors and heap space overwrites.
-
-USE_DL_PREFIX            default: NOT defined
-  Causes compiler to prefix all public routines with the string 'dl'.
-  This can be useful when you only want to use this malloc in one part
-  of a program, using your regular system malloc elsewhere.
-
-ABORT                    default: defined as abort()
-  Defines how to abort on failed checks.  On most systems, a failed
-  check cannot die with an "assert" or even print an informative
-  message, because the underlying print routines in turn call malloc,
-  which will fail again.  Generally, the best policy is to simply call
-  abort(). It's not very useful to do more than this because many
-  errors due to overwriting will show up as address faults (null, odd
-  addresses etc) rather than malloc-triggered checks, so will also
-  abort.  Also, most compilers know that abort() does not return, so
-  can better optimize code conditionally calling it.
-
-PROCEED_ON_ERROR           default: defined as 0 (false)
-  Controls whether detected bad addresses cause them to bypassed
-  rather than aborting. If set, detected bad arguments to free and
-  realloc are ignored. And all bookkeeping information is zeroed out
-  upon a detected overwrite of freed heap space, thus losing the
-  ability to ever return it from malloc again, but enabling the
-  application to proceed. If PROCEED_ON_ERROR is defined, the
-  static variable malloc_corruption_error_count is compiled in
-  and can be examined to see if errors have occurred. This option
-  generates slower code than the default abort policy.
-
-DEBUG                    default: NOT defined
-  The DEBUG setting is mainly intended for people trying to modify
-  this code or diagnose problems when porting to new platforms.
-  However, it may also be able to better isolate user errors than just
-  using runtime checks.  The assertions in the check routines spell
-  out in more detail the assumptions and invariants underlying the
-  algorithms.  The checking is fairly extensive, and will slow down
-  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
-  set will attempt to check every non-mmapped allocated and free chunk
-  in the course of computing the summaries.
-
-ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
-  Debugging assertion failures can be nearly impossible if your
-  version of the assert macro causes malloc to be called, which will
-  lead to a cascade of further failures, blowing the runtime stack.
-  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
-  which will usually make debugging easier.
-
-MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
-  The action to take before "return 0" when malloc fails to be able to
-  return memory because there is none available.
-
-HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
-  True if this system supports sbrk or an emulation of it.
-
-MORECORE                  default: sbrk
-  The name of the sbrk-style system routine to call to obtain more
-  memory.  See below for guidance on writing custom MORECORE
-  functions. The type of the argument to sbrk/MORECORE varies across
-  systems.  It cannot be size_t, because it supports negative
-  arguments, so it is normally the signed type of the same width as
-  size_t (sometimes declared as "intptr_t").  It doesn't much matter
-  though. Internally, we only call it with arguments less than half
-  the max value of a size_t, which should work across all reasonable
-  possibilities, although sometimes generating compiler warnings.  See
-  near the end of this file for guidelines for creating a custom
-  version of MORECORE.
-
-MORECORE_CONTIGUOUS       default: 1 (true)
-  If true, take advantage of fact that consecutive calls to MORECORE
-  with positive arguments always return contiguous increasing
-  addresses.  This is true of unix sbrk. It does not hurt too much to
-  set it true anyway, since malloc copes with non-contiguities.
-  Setting it false when definitely non-contiguous saves time
-  and possibly wasted space it would take to discover this though.
-
-MORECORE_CANNOT_TRIM      default: NOT defined
-  True if MORECORE cannot release space back to the system when given
-  negative arguments. This is generally necessary only if you are
-  using a hand-crafted MORECORE function that cannot handle negative
-  arguments.
-
-HAVE_MMAP                 default: 1 (true)
-  True if this system supports mmap or an emulation of it.  If so, and
-  HAVE_MORECORE is not true, MMAP is used for all system
-  allocation. If set and HAVE_MORECORE is true as well, MMAP is
-  primarily used to directly allocate very large blocks. It is also
-  used as a backup strategy in cases where MORECORE fails to provide
-  space from system. Note: A single call to MUNMAP is assumed to be
-  able to unmap memory that may have be allocated using multiple calls
-  to MMAP, so long as they are adjacent.
-
-HAVE_MREMAP               default: 1 on linux, else 0
-  If true realloc() uses mremap() to re-allocate large blocks and
-  extend or shrink allocation spaces.
-
-MMAP_CLEARS               default: 1 on unix
-  True if mmap clears memory so calloc doesn't need to. This is true
-  for standard unix mmap using /dev/zero.
-
-USE_BUILTIN_FFS            default: 0 (i.e., not used)
-  Causes malloc to use the builtin ffs() function to compute indices.
-  Some compilers may recognize and intrinsify ffs to be faster than the
-  supplied C version. Also, the case of x86 using gcc is special-cased
-  to an asm instruction, so is already as fast as it can be, and so
-  this setting has no effect. (On most x86s, the asm version is only
-  slightly faster than the C version.)
-
-malloc_getpagesize         default: derive from system includes, or 4096.
-  The system page size. To the extent possible, this malloc manages
-  memory from the system in page-size units.  This may be (and
-  usually is) a function rather than a constant. This is ignored
-  if WIN32, where page size is determined using getSystemInfo during
-  initialization.
-
-USE_DEV_RANDOM             default: 0 (i.e., not used)
-  Causes malloc to use /dev/random to initialize secure magic seed for
-  stamping footers. Otherwise, the current time is used.
-
-NO_MALLINFO                default: 0
-  If defined, don't compile "mallinfo". This can be a simple way
-  of dealing with mismatches between system declarations and
-  those in this file.
-
-MALLINFO_FIELD_TYPE        default: size_t
-  The type of the fields in the mallinfo struct. This was originally
-  defined as "int" in SVID etc, but is more usefully defined as
-  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
-
-REALLOC_ZERO_BYTES_FREES    default: not defined
-  This should be set if a call to realloc with zero bytes should 
-  be the same as a call to free. Some people think it should. Otherwise, 
-  since this malloc returns a unique pointer for malloc(0), so does 
-  realloc(p, 0).
-
-LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
-LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
-LACKS_STDLIB_H                default: NOT defined unless on WIN32
-  Define these if your system does not have these header files.
-  You might need to manually insert some of the declarations they provide.
-
-DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
-                                system_info.dwAllocationGranularity in WIN32,
-                                otherwise 64K.
-      Also settable using mallopt(M_GRANULARITY, x)
-  The unit for allocating and deallocating memory from the system.  On
-  most systems with contiguous MORECORE, there is no reason to
-  make this more than a page. However, systems with MMAP tend to
-  either require or encourage larger granularities.  You can increase
-  this value to prevent system allocation functions to be called so
-  often, especially if they are slow.  The value must be at least one
-  page and must be a power of two.  Setting to 0 causes initialization
-  to either page size or win32 region size.  (Note: In previous
-  versions of malloc, the equivalent of this option was called
-  "TOP_PAD")
-
-DEFAULT_TRIM_THRESHOLD    default: 2MB
-      Also settable using mallopt(M_TRIM_THRESHOLD, x)
-  The maximum amount of unused top-most memory to keep before
-  releasing via malloc_trim in free().  Automatic trimming is mainly
-  useful in long-lived programs using contiguous MORECORE.  Because
-  trimming via sbrk can be slow on some systems, and can sometimes be
-  wasteful (in cases where programs immediately afterward allocate
-  more large chunks) the value should be high enough so that your
-  overall system performance would improve by releasing this much
-  memory.  As a rough guide, you might set to a value close to the
-  average size of a process (program) running on your system.
-  Releasing this much memory would allow such a process to run in
-  memory.  Generally, it is worth tuning trim thresholds when a
-  program undergoes phases where several large chunks are allocated
-  and released in ways that can reuse each other's storage, perhaps
-  mixed with phases where there are no such chunks at all. The trim
-  value must be greater than page size to have any useful effect.  To
-  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
-  some people use of mallocing a huge space and then freeing it at
-  program startup, in an attempt to reserve system memory, doesn't
-  have the intended effect under automatic trimming, since that memory
-  will immediately be returned to the system.
-
-DEFAULT_MMAP_THRESHOLD       default: 256K
-      Also settable using mallopt(M_MMAP_THRESHOLD, x)
-  The request size threshold for using MMAP to directly service a
-  request. Requests of at least this size that cannot be allocated
-  using already-existing space will be serviced via mmap.  (If enough
-  normal freed space already exists it is used instead.)  Using mmap
-  segregates relatively large chunks of memory so that they can be
-  individually obtained and released from the host system. A request
-  serviced through mmap is never reused by any other request (at least
-  not directly; the system may just so happen to remap successive
-  requests to the same locations).  Segregating space in this way has
-  the benefits that: Mmapped space can always be individually released
-  back to the system, which helps keep the system level memory demands
-  of a long-lived program low.  Also, mapped memory doesn't become
-  `locked' between other chunks, as can happen with normally allocated
-  chunks, which means that even trimming via malloc_trim would not
-  release them.  However, it has the disadvantage that the space
-  cannot be reclaimed, consolidated, and then used to service later
-  requests, as happens with normal chunks.  The advantages of mmap
-  nearly always outweigh disadvantages for "large" chunks, but the
-  value of "large" may vary across systems.  The default is an
-  empirically derived value that works well in most systems. You can
-  disable mmap by setting to MAX_SIZE_T.

-  independent_calloc(size_t n_elements, size_t element_size, void* chunks[]);
-
-  independent_calloc is similar to calloc, but instead of returning a
-  single cleared space, it returns an array of pointers to n_elements
-  independent elements that can hold contents of size elem_size, each
-  of which starts out cleared, and can be independently freed,
-  realloc'ed etc. The elements are guaranteed to be adjacently
-  allocated (this is not guaranteed to occur with multiple callocs or
-  mallocs), which may also improve cache locality in some
-  applications.
-
-  The "chunks" argument is optional (i.e., may be null, which is
-  probably the most typical usage). If it is null, the returned array
-  is itself dynamically allocated and should also be freed when it is
-  no longer needed. Otherwise, the chunks array must be of at least
-  n_elements in length. It is filled in with the pointers to the
-  chunks.
-
-  In either case, independent_calloc returns this pointer array, or
-  null if the allocation failed.  If n_elements is zero and "chunks"
-  is null, it returns a chunk representing an array with zero elements
-  (which should be freed if not wanted).
-
-  Each element must be individually freed when it is no longer
-  needed. If you'd like to instead be able to free all at once, you
-  should instead use regular calloc and assign pointers into this
-  space to represent elements.  (In this case though, you cannot
-  independently free elements.)
-
-  independent_calloc simplifies and speeds up implementations of many
-  kinds of pools.  It may also be useful when constructing large data
-  structures that initially have a fixed number of fixed-sized nodes,
-  but the number is not known at compile time, and some of the nodes
-  may later need to be freed. For example:
-
-  struct Node { int item; struct Node* next; };
-
-  struct Node* build_list() {
-    struct Node** pool;
-    int n = read_number_of_nodes_needed();
-    if (n <= 0) return 0;
-    pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);
-    if (pool == 0) die();
-    // organize into a linked list...
-    struct Node* first = pool[0];
-    for (i = 0; i < n-1; ++i)
-      pool[i]->next = pool[i+1];
-    free(pool);     // Can now free the array (or not, if it is needed later)

-  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
-
-  independent_comalloc allocates, all at once, a set of n_elements
-  chunks with sizes indicated in the "sizes" array.    It returns
-  an array of pointers to these elements, each of which can be
-  independently freed, realloc'ed etc. The elements are guaranteed to
-  be adjacently allocated (this is not guaranteed to occur with
-  multiple callocs or mallocs), which may also improve cache locality
-  in some applications.
-
-  The "chunks" argument is optional (i.e., may be null). If it is null
-  the returned array is itself dynamically allocated and should also
-  be freed when it is no longer needed. Otherwise, the chunks array
-  must be of at least n_elements in length. It is filled in with the
-  pointers to the chunks.
-
-  In either case, independent_comalloc returns this pointer array, or
-  null if the allocation failed.  If n_elements is zero and chunks is
-  null, it returns a chunk representing an array with zero elements
-  (which should be freed if not wanted).
-
-  Each element must be individually freed when it is no longer
-  needed. If you'd like to instead be able to free all at once, you
-  should instead use a single regular malloc, and assign pointers at
-  particular offsets in the aggregate space. (In this case though, you
-  cannot independently free elements.)
-
-  independent_comallac differs from independent_calloc in that each
-  element may have a different size, and also that it does not
-  automatically clear elements.
-
-  independent_comalloc can be used to speed up allocation in cases
-  where several structs or objects must always be allocated at the
-  same time.  For example:
-
-  struct Head { ... }
-  struct Foot { ... }
-
-  void send_message(char* msg) {
-    int msglen = strlen(msg);
-    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
-    void* chunks[3];
-    if (independent_comalloc(3, sizes, chunks) == 0)
-      die();
-    struct Head* head = (struct Head*)(chunks[0]);
-    char*        body = (char*)(chunks[1]);
-    struct Foot* foot = (struct Foot*)(chunks[2]);
-    // ...
-  }
-
-  In general though, independent_comalloc is worth using only for
-  larger values of n_elements. For small values, you probably won't
-  detect enough difference from series of malloc calls to bother.
-
-  Overuse of independent_comalloc can increase overall memory usage,
-  since it cannot reuse existing noncontiguous small chunks that
-  might be available for some of the elements.

-/* -----------------------  Chunk representations ------------------------ */

-/*
-  (The following includes lightly edited explanations by Colin Plumb.)
-
-  The malloc_chunk declaration below is misleading (but accurate and
-  necessary).  It declares a "view" into memory allowing access to
-  necessary fields at known offsets from a given base.
-
-  Chunks of memory are maintained using a `boundary tag' method as
-  originally described by Knuth.  (See the paper by Paul Wilson
-  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
-  techniques.)  Sizes of free chunks are stored both in the front of
-  each chunk and at the end.  This makes consolidating fragmented
-  chunks into bigger chunks fast.  The head fields also hold bits
-  representing whether chunks are free or in use.
-
-  Here are some pictures to make it clearer.  They are "exploded" to
-  show that the state of a chunk can be thought of as extending from
-  the high 31 bits of the head field of its header through the
-  prev_foot and PINUSE_BIT bit of the following chunk header.
-
-  A chunk that's in use looks like:
-
-   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-           | Size of previous chunk (if P = 1)                             |

-         +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P|
-         | Size of this chunk                                         1| +-+

-         +-                                                             -+

-         +-                                                             -+
-         |                                                               :
-         +-      size - sizeof(size_t) available payload bytes          -+
-         :                                                               |
- chunk-> +-                                                             -+

-  Note that since we always merge adjacent free chunks, the chunks
-  adjacent to a free chunk must be in use.
-
-  Given a pointer to a chunk (which can be derived trivially from the
-  payload pointer) we can, in O(1) time, find out whether the adjacent
-  chunks are free, and if so, unlink them from the lists that they
-  are on and merge them with the current chunk.
-
-  Chunks always begin on even word boundaries, so the mem portion
-  (which is returned to the user) is also on an even word boundary, and
-  thus at least double-word aligned.
-
-  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
-  chunk size (which is always a multiple of two words), is an in-use
-  bit for the *previous* chunk.  If that bit is *clear*, then the
-  word before the current chunk size contains the previous chunk
-  size, and can be used to find the front of the previous chunk.
-  The very first chunk allocated always has this bit set, preventing
-  access to non-existent (or non-owned) memory. If pinuse is set for
-  any given chunk, then you CANNOT determine the size of the
-  previous chunk, and might even get a memory addressing fault when
-  trying to do so.
-
-  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
-  the chunk size redundantly records whether the current chunk is
-  inuse. This redundancy enables usage checks within free and realloc,
-  and reduces indirection when freeing and consolidating chunks.
-
-  Each freshly allocated chunk must have both cinuse and pinuse set.
-  That is, each allocated chunk borders either a previously allocated
-  and still in-use chunk, or the base of its memory arena. This is
-  ensured by making all allocations from the the `lowest' part of any
-  found chunk.  Further, no free chunk physically borders another one,
-  so each free chunk is known to be preceded and followed by either
-  inuse chunks or the ends of memory.
-
-  Note that the `foot' of the current chunk is actually represented
-  as the prev_foot of the NEXT chunk. This makes it easier to
-  deal with alignments etc but can be very confusing when trying
-  to extend or adapt this code.
-
-  The exceptions to all this are
-
-     1. The special chunk `top' is the top-most available chunk (i.e.,
-        the one bordering the end of available memory). It is treated
-        specially.  Top is never included in any bin, is used only if
-        no other chunk is available, and is released back to the
-        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
-        the top chunk is treated as larger (and thus less well
-        fitting) than any other available chunk.  The top chunk
-        doesn't update its trailing size field since there is no next
-        contiguous chunk that would have to index off it. However,
-        space is still allocated for it (TOP_FOOT_SIZE) to enable
-        separation or merging when space is extended.
-
-     3. Chunks allocated via mmap, which have the lowest-order bit
-        (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
-        PINUSE_BIT in their head fields.  Because they are allocated
-        one-by-one, each must carry its own prev_foot field, which is
-        also used to hold the offset this chunk has within its mmapped
-        region, which is needed to preserve alignment. Each mmapped
-        chunk is trailed by the first two fields of a fake next-chunk
-        for sake of usage checks.

-
-  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
-  of the same size are arranged in a circularly-linked list, with only
-  the oldest chunk (the next to be used, in our FIFO ordering)
-  actually in the tree.  (Tree members are distinguished by a non-null
-  parent pointer.)  If a chunk with the same size an an existing node
-  is inserted, it is linked off the existing node using pointers that
-  work in the same way as fd/bk pointers of small chunks.
-
-  Each tree contains a power of 2 sized range of chunk sizes (the
-  smallest is 0x100 <= x < 0x180), which is is divided in half at each
-  tree level, with the chunks in the smaller half of the range (0x100
-  <= x < 0x140 for the top nose) in the left subtree and the larger
-  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
-  done by inspecting individual bits.
-
-  Using these rules, each node's left subtree contains all smaller
-  sizes than its right subtree.  However, the node at the root of each
-  subtree has no particular ordering relationship to either.  (The
-  dividing line between the subtree sizes is based on trie relation.)
-  If we remove the last chunk of a given size from the interior of the
-  tree, we need to replace it with a leaf node.  The tree ordering
-  rules permit a node to be replaced by any leaf below it.
-
-  The smallest chunk in a tree (a common operation in a best-fit
-  allocator) can be found by walking a path to the leftmost leaf in
-  the tree.  Unlike a usual binary tree, where we follow left child
-  pointers until we reach a null, here we follow the right child
-  pointer any time the left one is null, until we reach a leaf with
-  both child pointers null. The smallest chunk in the tree will be
-  somewhere along that path.
-
-  The worst case number of steps to add, find, or remove a node is
-  bounded by the number of bits differentiating chunks within
-  bins. Under current bin calculations, this ranges from 6 up to 21
-  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
-  is of course much better.

-/* ----------------------------- Segments -------------------------------- */
-
-/*
-  Each malloc space may include non-contiguous segments, held in a
-  list headed by an embedded malloc_segment record representing the
-  top-most space. Segments also include flags holding properties of
-  the space. Large chunks that are directly allocated by mmap are not
-  included in this list. They are instead independently created and
-  destroyed without otherwise keeping track of them.
-
-  Segment management mainly comes into play for spaces allocated by
-  MMAP.  Any call to MMAP might or might not return memory that is
-  adjacent to an existing segment.  MORECORE normally contiguously
-  extends the current space, so this space is almost always adjacent,
-  which is simpler and faster to deal with. (This is why MORECORE is
-  used preferentially to MMAP when both are available -- see
-  sys_alloc.)  When allocating using MMAP, we don't use any of the
-  hinting mechanisms (inconsistently) supported in various
-  implementations of unix mmap, or distinguish reserving from
-  committing memory. Instead, we just ask for space, and exploit
-  contiguity when we get it.  It is probably possible to do
-  better than this on some systems, but no general scheme seems
-  to be significantly better.
-
-  Management entails a simpler variant of the consolidation scheme
-  used for chunks to reduce fragmentation -- new adjacent memory is
-  normally prepended or appended to an existing segment. However,
-  there are limitations compared to chunk consolidation that mostly
-  reflect the fact that segment processing is relatively infrequent
-  (occurring only when getting memory from system) and that we
-  don't expect to have huge numbers of segments:
-
-  * Segments are not indexed, so traversal requires linear scans.  (It
-    would be possible to index these, but is not worth the extra
-    overhead and complexity for most programs on most platforms.)
-  * New segments are only appended to old ones when holding top-most
-    memory; if they cannot be prepended to others, they are held in
-    different segments.
-
-  Except for the top-most segment of an mstate, each segment record
-  is kept at the tail of its segment. Segments are added by pushing
-  segment records onto the list headed by &mstate.seg for the
-  containing mstate.
-
-  Segment flags control allocation/merge/deallocation policies:
-  * If EXTERN_BIT set, then we did not allocate this segment,
-    and so should not try to deallocate or merge with others.
-    (This currently holds only for the initial segment passed
-    into create_mspace_with_base.)
-  * If IS_MMAPPED_BIT set, the segment may be merged with
-    other surrounding mmapped segments and trimmed/de-allocated
-    using munmap.
-  * If neither bit is set, then the segment was obtained using
-    MORECORE so can be merged with surrounding MORECORE'd segments
-    and deallocated/trimmed using MORECORE with negative arguments.

-
-/*
-   A malloc_state holds all of the bookkeeping for a space.
-   The main fields are:
-
-  Top
-    The topmost chunk of the currently active segment. Its size is
-    cached in topsize.  The actual size of topmost space is
-    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
-    fenceposts and segment records if necessary when getting more
-    space from the system.  The size at which to autotrim top is
-    cached from mparams in trim_check, except that it is disabled if
-    an autotrim fails.
-
-  Designated victim (dv)
-    This is the preferred chunk for servicing small requests that
-    don't have exact fits.  It is normally the chunk split off most
-    recently to service another small request.  Its size is cached in
-    dvsize. The link fields of this chunk are not maintained since it
-    is not kept in a bin.
-
-  SmallBins
-    An array of bin headers for free chunks.  These bins hold chunks
-    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
-    chunks of all the same size, spaced 8 bytes apart.  To simplify
-    use in double-linked lists, each bin header acts as a malloc_chunk
-    pointing to the real first node, if it exists (else pointing to
-    itself).  This avoids special-casing for headers.  But to avoid
-    waste, we allocate only the fd/bk pointers of bins, and then use
-    repositioning tricks to treat these as the fields of a chunk.
-
-  TreeBins
-    Treebins are pointers to the roots of trees holding a range of
-    sizes. There are 2 equally spaced treebins for each power of two
-    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
-    larger.
-
-  Bin maps
-    There is one bit map for small bins ("smallmap") and one for
-    treebins ("treemap).  Each bin sets its bit when non-empty, and
-    clears the bit when empty.  Bit operations are then used to avoid
-    bin-by-bin searching -- nearly all "search" is done without ever
-    looking at bins that won't be selected.  The bit maps
-    conservatively use 32 bits per map word, even if on 64bit system.
-    For a good description of some of the bit-based techniques used
-    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
-    supplement at http://hackersdelight.org/). Many of these are
-    intended to reduce the branchiness of paths through malloc etc, as
-    well as to reduce the number of memory locations read or written.
-
-  Segments
-    A list of segments headed by an embedded malloc_segment record
-    representing the initial space.
-
-  Address check support
-    The least_addr field is the least address ever obtained from
-    MORECORE or MMAP. Attempted frees and reallocs of any address less
-    than this are trapped (unless INSECURE is defined).
-
-  Magic tag
-    A cross-check field that should always hold same value as mparams.magic.
-
-  Flags
-    Bits recording whether to use MMAP, locks, or contiguous MORECORE
-
-  Statistics
-    Each space keeps track of current and maximum system memory
-    obtained via MORECORE or MMAP.
-
-  Locking
-    If USE_LOCKS is defined, the "mutex" lock is acquired and released
-    around every public call using this mspace.

-  For security, the main invariant is that malloc/free/etc never
-  writes to a static address other than malloc_state, unless static
-  malloc_state itself has been corrupted, which cannot occur via
-  malloc (because of these checks). In essence this means that we
-  believe all pointers, sizes, maps etc held in malloc_state, but
-  check all of those linked or offsetted from other embedded data
-  structures.  These checks are interspersed with main code in a way
-  that tends to minimize their run-time cost.
-
-  When FOOTERS is defined, in addition to range checking, we also
-  verify footer fields of inuse chunks, which can be used guarantee
-  that the mstate controlling malloc/free is intact.  This is a
-  streamlined version of the approach described by William Robertson
-  et al in "Run-time Detection of Heap-based Overflows" LISA'03
-  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
-  of an inuse chunk holds the xor of its mstate and a random seed,
-  that is checked upon calls to free() and realloc().  This is
-  (probablistically) unguessable from outside the program, but can be
-  computed by any code successfully malloc'ing any chunk, so does not
-  itself provide protection against code that has already broken
-  security through some other means.  Unlike Robertson et al, we
-  always dynamically check addresses of all offset chunks (previous,
-  next, etc). This turns out to be cheaper than relying on hashes.

-/* -------------------- Alternative MORECORE functions ------------------- */
-
-/*
-  Guidelines for creating a custom version of MORECORE:
-
-  * For best performance, MORECORE should allocate in multiples of pagesize.
-  * MORECORE may allocate more memory than requested. (Or even less,
-      but this will usually result in a malloc failure.)
-  * MORECORE must not allocate memory when given argument zero, but
-      instead return one past the end address of memory from previous
-      nonzero call.
-  * For best performance, consecutive calls to MORECORE with positive
-      arguments should return increasing addresses, indicating that
-      space has been contiguously extended.
-  * Even though consecutive calls to MORECORE need not return contiguous
-      addresses, it must be OK for malloc'ed chunks to span multiple
-      regions in those cases where they do happen to be contiguous.
-  * MORECORE need not handle negative arguments -- it may instead
-      just return MFAIL when given negative arguments.
-      Negative arguments are always multiples of pagesize. MORECORE
-      must not misinterpret negative args as large positive unsigned
-      args. You can suppress all such calls from even occurring by defining
-      MORECORE_CANNOT_TRIM,
-
-  As an example alternative MORECORE, here is a custom allocator
-  kindly contributed for pre-OSX macOS.  It uses virtually but not
-  necessarily physically contiguous non-paged memory (locked in,
-  present and won't get swapped out).  You can use it by uncommenting
-  this section, adding some #includes, and setting up the appropriate
-  defines above:
-
-      #define MORECORE osMoreCore
-
-  There is also a shutdown routine that should somehow be called for
-  cleanup upon program exit.
-
-  #define MAX_POOL_ENTRIES 100
-  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
-  static int next_os_pool;
-  void *our_os_pools[MAX_POOL_ENTRIES];
-
-  void *osMoreCore(int size)
-  {
-    void *ptr = 0;
-    static void *sbrk_top = 0;
-
-    if (size > 0)
-    {
-      if (size < MINIMUM_MORECORE_SIZE)
-         size = MINIMUM_MORECORE_SIZE;
-      if (CurrentExecutionLevel() == kTaskLevel)
-         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
-      if (ptr == 0)
-      {
-        return (void *) MFAIL;
-      }
-      // save ptrs so they can be freed during cleanup
-      our_os_pools[next_os_pool] = ptr;
-      next_os_pool++;
-      ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK);
-      sbrk_top = (char *) ptr + size;
-      return ptr;
-    }
-    else if (size < 0)
-    {
-      // we don't currently support shrink behavior
-      return (void *) MFAIL;
-    }
-    else
-    {
-      return sbrk_top;
-    }
-  }
-
-  // cleanup any allocated memory pools
-  // called as last thing before shutting down driver
-
-  void osCleanupMem(void)
-  {
-    void **ptr;

+
+* Version 2.8.6 Wed Aug 29 06:57:58 2012  Doug Lea
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.6.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (minimum)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                          8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                          8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+       It is also possible to limit the maximum total allocatable
+       space, using malloc_set_footprint_limit. This is not
+       designed as a security feature in itself (calls to set limits
+       are not screened or privileged), but may be useful as one
+       aspect of a secure implementation.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined non-zero
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with a lock. By default, this uses a plain
+       pthread mutex, win32 critical section, or a spin-lock if if
+       available for the platform and not disabled by setting
+       USE_SPIN_LOCKS=0.  However, if USE_RECURSIVE_LOCKS is defined,
+       recursive versions are used instead (which are not required for
+       base functionality but may be needed in layered extensions).
+       Using a global lock is not especially fast, and can be a major
+       bottleneck.  It is designed only to provide minimal protection
+       in concurrent environments, and to provide a basis for
+       extensions.  If you are using malloc in a concurrent program,
+       consider instead using nedmalloc
+       (http://www.nedprod.com/programs/portable/nedmalloc/) or
+       ptmalloc (See http://www.malloc.de), which are derived from
+       versions of this malloc.
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1. In real-time
+  applications, you can optionally suppress segment traversals using
+  NO_SEGMENT_TRAVERSAL, which assures bounded execution even when
+  system allocators return non-contiguous spaces, at the typical
+  expense of carrying around more memory and increased fragmentation.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces. Normally, this requires use of locks.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted. You can also
+use the symbolic values MAX_SIZE_T, SIZE_T_ONE, etc below.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix. Beware that there seem to be some
+  cases where this malloc might not be a pure drop-in replacement for
+  Win32 malloc: Random-looking failures from Win32 GDI API's (eg;
+  SetDIBits()) may be due to bugs in some video driver implementations
+  when pixel buffers are malloc()ed, and the region spans more than
+  one VirtualAlloc()ed region. Because dlmalloc uses a small (64Kb)
+  default granularity, pixel buffers may straddle virtual allocation
+  regions more often than when using the Microsoft allocator.  You can
+  avoid this by using VirtualAlloc() and VirtualFree() for all pixel
+  buffers rather than using malloc().  If this is not possible,
+  recompile this malloc with a larger DEFAULT_GRANULARITY. Note:
+  in cases where MSC and gcc (cygwin) are known to differ on WIN32,
+  conditions use _MSC_VER to distinguish them.
+
+DLMALLOC_EXPORT       default: extern
+  Defines how public APIs are declared. If you want to export via a
+  Windows DLL, you might define this as
+    #define DLMALLOC_EXPORT extern  __declspec(dllexport)
+  If you want a POSIX ELF shared object, you might use
+    #define DLMALLOC_EXPORT extern __attribute__((visibility("default")))
+
+MALLOC_ALIGNMENT         default: (size_t)(2 * sizeof(void *))
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.) If set to a
+  non-zero value other than 1, locks are used, but their
+  implementation is left out, so lock functions must be supplied manually,
+  as described below.
+
+USE_SPIN_LOCKS           default: 1 iff USE_LOCKS and spin locks available
+  If true, uses custom spin locks for locking. This is currently
+  supported only gcc >= 4.1, older gccs on x86 platforms, and recent
+  MS compilers.  Otherwise, posix locks or win32 critical sections are
+  used.
+
+USE_RECURSIVE_LOCKS      default: not defined
+  If defined nonzero, uses recursive (aka reentrant) locks, otherwise
+  uses plain mutexes. This is not required for malloc proper, but may
+  be needed for layered allocators such as nedmalloc.
+
+LOCK_AT_FORK            default: not defined
+  If defined nonzero, performs pthread_atfork upon initialization
+  to initialize child lock while holding parent lock. The implementation
+  assumes that pthread locks (not custom locks) are being used. In other
+  cases, you may need to customize the implementation.
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+MALLOC_INSPECT_ALL       default: NOT defined
+  If defined, compiles malloc_inspect_all and mspace_inspect_all, that
+  perform traversal of all heap space.  Unless access to these
+  functions is otherwise restricted, you probably do not want to
+  include them in secure implementations.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.
+
+MORECORE_CONTIGUOUS       default: 1 (true) if HAVE_MORECORE
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+NO_SEGMENT_TRAVERSAL       default: 0
+  If non-zero, suppresses traversals of memory segments
+  returned by either MORECORE or CALL_MMAP. This disables
+  merging of segments that are contiguous, and selectively
+  releasing them to the OS if unused, but bounds execution times.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 except on WINCE.
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero and on WIN32 except for WINCE.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. Similarly for Win32 under recent MS compilers.
+  (On most x86s, the asm version is only slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+NO_MALLOC_STATS            default: 0
+  If defined, don't compile "malloc_stats". This avoids calls to
+  fprintf and bringing in stdio dependencies you might not want.
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should
+  be the same as a call to free. Some people think it should. Otherwise,
+  since this malloc returns a unique pointer for malloc(0), so does
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H LACKS_SCHED_H LACKS_TIME_H  default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                                system_info.dwAllocationGranularity in WIN32,
+                                otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.
+
+MAX_RELEASE_CHECK_RATE   default: 4095 unless not HAVE_MMAP
+  The number of consolidated frees between checks to release
+  unused segments when freeing. When using non-contiguous segments,
+  especially with multiple mspaces, checking only for topmost space
+  doesn't always suffice to trigger trimming. To compensate for this,
+  free() will, with a period of MAX_RELEASE_CHECK_RATE (or the
+  current number of segments, if greater) try to release unused
+  segments to the OS when freeing chunks that result in
+  consolidation. The best value for this parameter is a compromise
+  between slowing down frees with relatively costly checks that
+  rarely trigger versus holding on to unused memory. To effectively
+  disable, set to MAX_SIZE_T. This may lead to a very slight speed
+  improvement at the expense of carrying around more memory.

+  When locks are defined, there is one global lock, plus
+  one per-mspace lock.
+
+  The global lock_ensures that mparams.magic and other unique
+  mparams values are initialized only once. It also protects
+  sequences of calls to MORECORE.  In many cases sys_alloc requires
+  two calls, that should not be interleaved with calls by other
+  threads.  This does not protect against direct calls to MORECORE
+  by other threads not using this lock, so there is still code to
+  cope the best we can on interference.
+
+  Per-mspace locks surround calls to malloc, free, etc.
+  By default, locks are simple non-reentrant mutexes.
+
+  Because lock-protected regions generally have bounded times, it is
+  OK to use the supplied simple spinlocks. Spinlocks are likely to
+  improve performance for lightly contended applications, but worsen
+  performance under heavy contention.
+
+  If USE_LOCKS is > 1, the definitions of lock routines here are

+
+/*
+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+           | Size of previous chunk (if P = 0)                             |

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse (unless the chunk is mmapped). This redundancy enables usage
+  checks within free and realloc, and reduces indirection when freeing
+  and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, have both cinuse and pinuse bits
+        cleared in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If USE_MMAP_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+/*
+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Max allowed footprint
+    The maximum allowed bytes to allocate from system (zero means no limit)
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probabalistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;
+  void *our_os_pools[MAX_POOL_ENTRIES];

+  void *osMoreCore(int size)
+  {
+    void *ptr = 0;
+    static void *sbrk_top = 0;
+
+    if (size > 0)
+    {
+      if (size < MINIMUM_MORECORE_SIZE)
+         size = MINIMUM_MORECORE_SIZE;
+      if (CurrentExecutionLevel() == kTaskLevel)
+         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
+      if (ptr == 0)

+      * Allow override of MALLOC_ALIGNMENT (Thanks to Ruud Waij for
+        helping test this.)
+      * memalign: check alignment arg
+      * realloc: don't try to shift chunks backwards, since this
+        leads to  more fragmentation in some programs and doesn't
+        seem to help in any others.
+      * Collect all cases in malloc requiring system memory into sysmalloc
+      * Use mmap as backup to sbrk
+      * Place all internal state in malloc_state
+      * Introduce fastbins (although similar to 2.5.1)
+      * Many minor tunings and cosmetic improvements
+      * Introduce USE_PUBLIC_MALLOC_WRAPPERS, USE_MALLOC_LOCK
+      * Introduce MALLOC_FAILURE_ACTION, MORECORE_CONTIGUOUS
+        Thanks to Tony E. Bennett <tbennett@nvidia.com> and others.
+      * Include errno.h to support default failure action.
+
+    V2.6.6 Sun Dec  5 07:42:19 1999  Doug Lea  (dl at gee)
+      * return null for negative arguments
+      * Added Several WIN32 cleanups from Martin C. Fong <mcfong at yahoo.com>
+         * Add 'LACKS_SYS_PARAM_H' for those systems without 'sys/param.h'
+          (e.g. WIN32 platforms)
+         * Cleanup header file inclusion for WIN32 platforms
+         * Cleanup code to avoid Microsoft Visual C++ compiler complaints
+         * Add 'USE_DL_PREFIX' to quickly allow co-existence with existing
+           memory allocation routines
+         * Set 'malloc_getpagesize' for WIN32 platforms (needs more work)
+         * Use 'assert' rather than 'ASSERT' in WIN32 code to conform to
+           usage of 'assert' in non-WIN32 code
+         * Improve WIN32 'sbrk()' emulation's 'findRegion()' routine to
+           avoid infinite loop
+      * Always call 'fREe()' rather than 'free()'
+
+    V2.6.5 Wed Jun 17 15:57:31 1998  Doug Lea  (dl at gee)
+      * Fixed ordering problem with boundary-stamping
+
+    V2.6.3 Sun May 19 08:17:58 1996  Doug Lea  (dl at gee)
+      * Added pvalloc, as recommended by H.J. Liu
+      * Added 64bit pointer support mainly from Wolfram Gloger
+      * Added anonymously donated WIN32 sbrk emulation
+      * Malloc, calloc, getpagesize: add optimizations from Raymond Nijssen
+      * malloc_extend_top: fix mask error that caused wastage after
+        foreign sbrks
+      * Add linux mremap support code from HJ Liu
+
+    V2.6.2 Tue Dec  5 06:52:55 1995  Doug Lea  (dl at gee)
+      * Integrated most documentation with the code.
+      * Add support for mmap, with help from
+        Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Use last_remainder in more cases.
+      * Pack bins using idea from  colin@nyx10.cs.du.edu
+      * Use ordered bins instead of best-fit threshold
+      * Eliminate block-local decls to simplify tracing and debugging.
+      * Support another case of realloc via move into top
+      * Fix error occurring when initial sbrk_base not word-aligned.
+      * Rely on page size for units instead of SBRK_UNIT to
+        avoid surprises about sbrk alignment conventions.
+      * Add mallinfo, mallopt. Thanks to Raymond Nijssen
+        (raymond@es.ele.tue.nl) for the suggestion.
+      * Add `pad' argument to malloc_trim and top_pad mallopt parameter.
+      * More precautions for cases where other routines call sbrk,
+        courtesy of Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Added macros etc., allowing use in linux libc from
+        H.J. Lu (hjl@gnu.ai.mit.edu)
+      * Inverted this history list
+
+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+        the work required to undo bad preallocations exceeds
+        the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since
+        no scheme using them consistently outperforms those that don't
+        given above changes.
+      * Use best fit for very large chunks to prevent some worst-cases.
+      * Added some support for debugging
+
+    V2.6.0 Sat Nov  4 07:05:23 1995  Doug Lea  (dl at gee)
+      * Removed footers when chunks are in use. Thanks to
+        Paul Wilson (wilson@cs.texas.edu) for the suggestion.
+
+    V2.5.4 Wed Nov  1 07:54:51 1995  Doug Lea  (dl at gee)
+      * Added malloc_trim, with help from Wolfram Gloger
+        (wmglo@Dent.MED.Uni-Muenchen.DE).
+
+    V2.5.3 Tue Apr 26 10:16:01 1994  Doug Lea  (dl at g)
+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin@nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+         (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers
+          from kpv@research.att.com
+
+    V2.5 Sat Aug  7 07:41:59 1993  Doug Lea  (dl at g.oswego.edu)
+      * removed potential for odd address access in prev_chunk
+      * removed dependency on getpagesize.h
+      * misc cosmetics and a bit more internal documentation
+      * anticosmetics: mangled names in macros to evade debugger strangeness
+      * tested on sparc, hp-700, dec-mips, rs6000
+          with gcc & native cc (hp, dec only) allowing
+          Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+         structure of old version,  but most details differ.)
