Fix an OOM-related regression in arena_tcache_fill_small() that caused cache corruption that would almost certainly expose the application to undefined behavior, usually in the form of an allocation request returning an already-allocated region, or somewhat less likely, a freed region that had already been returned to the arena, thus making it available to the arena for any purpose. This regression was introduced by 9c43c13a35220c10d97a886616899189daceb359 (Reverse tcache fill order.), and was present in all releases from 2.2.0 through 3.6.0. This resolves #98.
jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling, Valgrind integration, and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://www.canonware.com/jemalloc/
