Yay. I just checked it in.
* unexmacosx.c (unexec_realloc): Use malloc_default_zone to
determine the size of pointers alloced in unexed space instead
of using possibly invalid emacs_zone pointers. This fixes the
binary incompatibility problems caused by updates to libSystem.B.
If anybody is making binary distributions publicly available, you
should sync the change to unexmacosx.c and rebuild. And I invite
anyone to look into adding a pre-flight/post-flight script to the Mac
OS X installer to "backup" the apple-provided 21.1 binary if installing
into /usr/bin. Some people on versiontracker were complaining.
