- update to 2.15:
* Mikael Simberg and Tom "spot" Callaway have pointed out the
missing symbols issue when linking PPC or i386
builds.
* Roman Geissler has contributed a fix to nasty initialization
bug introduced in 2.13 (see github issue #1452 for one example
where it fails).
* spinlock delay support now has proper windows support.
Instead of simply sleeping, it uses WaitOnAddress (which is
basically windows equivalent of futexes). This improvement was
contributed by Lennox Ho.
* we now have basic QNX support (basic malloc + heap profiler)
championed by Xiang.Lin. Thanks! Do note, however, that QNX
doesn't provide SIGPROF ticks, so there will be no cpu profiler
support on this OS.
* several people have contributed various improvements to our
cmake build: Lennox Ho, Sergey Fedorov, Mateusz Jakub Fila. But
do note that cmake build is still incomplete and best-effort.
* Julian Schroeder have fixed generic_fp incompatibility with
ARM pointer auth.
* Mateusz Jakub Fila has contributed implementation of
mallocinfo2 function (64-bit version of mallinfo).
* Lennox Ho has contributed the ability to disable malloc
functions patching on windows when TCMALLOC_DISABLE_REPLACEMENT=1
environment variable is set.
* User poljak181 has contributed a fix to infinite recursion in
some cases of malloc hooks (or user-replaced operator new) and
MallocExtension::instance().
* Sergey Fedorov has contributed a fix to use MAP_ANON on some
older OSes without MAP_ANONYMOUS.
