Thanks.  Yes, that's probably the cause.  Unfortunately dynamically
linked libraries are the only choice for using most of the "system
frameworks" on Mac OS X.  I'm currently trying to determine whether some
variables in the libraries are somehow unexec'ed along with the Emacs
heap.  Of course this will cause a problem if the new libraries change
the variables' locations.  There aren't many tools available to look
into this.  But I'll figure out a way sooner or later.
