jemalloc 3.4.1 is now available. This version fixes a serious bug in the "arenas.extend" mallctl, as well as several minor issues.
- Fix a race in the "arenas.extend" mallctl that could cause memory corruption of internal data structures and subsequent crashes.
- Fix Valgrind integration flaws that caused Valgrind warnings about reads of uninitialized memory in:
+ arena chunk headers
+ internal zero-initialized data structures (relevant to tcache and prof code)
- Preserve errno during the first allocation. A readlink(2) call during initialization fails unless /etc/malloc.conf exists, so errno was typically set during the first allocation prior to this fix.
- Fix compilation warnings reported by gcc 4.8.1.
