Hi. I've just tagged gperftools 2.14.
This release has the following set of notable changes:
* Roman Geissler has contributed a fix to a 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 checker) 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.
* Yikai Zhao has contributed several fixes to important corner cases of generic_fp stacktrace method.
* 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 has fixed generic_fp incompatibility with ARM pointer auth.
* Mateusz Jakub Fila has contributed the mallocinfo2 function (64-bit version of mallinfo).
* Lennox Ho has updated C malloc extension shims to include {Set,Get}MemoryReleaseRate.
* Lennox Ho has contributed 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.
* the way we detect working ucontext->pc extraction method was reworked and is now fully compile-time as opposed to config-time. This means no more duplication and mismatches between autoconf and cmake bits in this area.
