It turns out some OSX system libraries (like CoreGraphics on 10.6) like to call malloc_zone_* functions, but giving them pointers that weren't allocated with the zone they are using. Possibly, they do malloc_zone_malloc(malloc_default_zone()) before we register the jemalloc zone, and malloc_zone_realloc(malloc_default_zone()) after. malloc_default_zone() returning a different value in both cases.
jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a stand-alone "portable" implementation that currently targets FreeBSD, Linux and Apple OS X. 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/
