The security update did not update the Carbon framework, although it
did update libSystem.

Hm, that implies to me that the unexec code rewrites the load commands
in some interesting and different manner than the apple-supplied emacs.
Note that /usr/bin/emacs works fine between updates with requiring
updates.

Hm, I see that the unexmacosx.c in FSF emacs CVS is different than
unexdyld.c in Darwin CVS. Perhaps you should try using that version of
unexec to narrow down the problem.
