Fix arena_size arena_new() computation to incorporate runs_avail_nclasses elements for runs_avail, rather than (runs_avail_nclasses - 1) elements. Since offsetof(arena_t, runs_avail) is used rather than sizeof(arena_t) for the first term of the computation, all of the runs_avail elements must be added into the second term. This bug was introduced (by Jason Evans) while merging pull request #330 as 3417a304ccde61ac1f68b436ec22c03f1d6824ec (Separate arena_avail trees).
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/
