Fix a chunk recycling bug that could cause the allocator to lose track of whether a chunk was zeroed. On FreeBSD, NetBSD, and OS X, it could cause corruption if allocating via sbrk(2) (unlikely unless running with the "dss:primary" option specified). This was completely harmless on Linux unless using mlockall(2) (and unlikely even then, unless the --disable-munmap configure option or the "dss:primary" option was specified). This regression was introduced in 3.1.0 by the mlockall(2)/madvise(2) interaction fix.
jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a "portable" implementation that currently targets FreeBSD, Linux, Apple OS X, and MinGW. 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. The ChangeLog file contains a brief summary of changes for each release. URL: http://www.canonware.com/jemalloc/
