Probably.
How about running the bootstrap temacs (the one that is dumped to
produce bootstrap-emacs) under GDB with a breakpoint in malloc, and
recording all calls to malloc with their callers? Then you could
compare that with a similar run for a pre-merge CVS, and look for some
callers that could potentially lead to corruption of the malloc chain
the the dumped executable.
