Fix the newsize argument to arena_run_trim_tail() that arena_dalloc_bin_run() passes. Previously, oldsize-newsize (i.e. the complement) was passed, which could erroneously cause dirty pages to be returned to the clean available runs tree. Prior to the CHUNK_MAP_ZEROED --> CHUNK_MAP_UNZEROED conversion, this bug merely caused dirty pages to be unaccounted for (and therefore never get purged), but with CHUNK_MAP_UNZEROED, this could cause dirty pages to be treated as zeroed (i.e. memory corruption). |

jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a stand-alone "portable" implementation that currently targets only Linux. jemalloc is included as the default allocator in the FreeBSD and NetBSD operating systems, and it is used by the Mozilla Firefox web browser on Microsoft Windows-related platforms. Depending on your needs, one of the other divergent versions may suit your needs better than this distribution. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. URL: http://www.canonware.com/jemalloc/
