* 3.5.0 (XXX)
This version focuses on refactoring and automated testing, though it also
includes some non-trivial heap profiling optimizations not mentioned below.
New features:
- Add the *allocx() API, which is a successor to the experimental *allocm()
API. The *allocx() functions are slightly simpler to use because they have
fewer parameters, they directly return the results of primary interest, and
mallocx()/rallocx() avoid the strict aliasing pitfall that
allocm()/rallocx() share with posix_memalign(). Note that *allocm() is
slated for removal in the next non-bugfix release.
- Add support for LinuxThreads.
Bug fixes:
- Unless heap profiling is enabled, disable floating point code and don't link
with libm. This, in combination with e.g. EXTRA_CFLAGS=-mno-sse on x64

point registers during dynamic lazy symbol loading, and the symbol loading
code uses whatever malloc the application happens to have linked/loaded
with, the result being potential floating point register corruption.
- Report ENOMEM rather than EINVAL if an OOM occurs during heap profiling
backtrace creation in imemalign(). This bug impacted posix_memalign() and
aligned_alloc().
- Fix a file descriptor leak in a prof_dump_maps() error path.
- Fix prof_dump() to close the dump file descriptor for all relevant error
paths.
- Fix rallocm() to use the arena specified by the ALLOCM_ARENA(s) flag for
allocation, not just deallocation.
- Fix a data race for large allocation stats counters.
- Fix a potential infinite loop during thread exit. This bug occurred on
Solaris, and could affect other platforms with similar pthreads TSD
implementations.
- Don't junk-fill reallocations unless usable size changes. This fixes a
violation of the *allocx()/*allocm() semantics.
- Fix growing large reallocation to junk fill new space.
- Fix huge deallocation to junk fill when munmap is disabled.
- Change the default private namespace prefix from empty to je_, and change
--with-private-namespace-prefix so that it prepends an additional prefix
rather than replacing je_. This reduces the likelihood of applications
which statically link jemalloc experiencing symbol name collisions.
- Add missing private namespace mangling (relevant when
--with-private-namespace is specified).
- Add and use JEMALLOC_INLINE_C so that static inline functions are marked as
static even for debug builds.
- Add a missing mutex unlock in a malloc_init_hard() error path. In practice
this error path is never executed.
- Fix numerous bugs in malloc_strotumax() error handling/reporting. These
bugs had no impact except for malformed inputs.
- Fix numerous bugs in malloc_snprintf(). These bugs were not exercised by
existing calls, so they had no impact.
