Core files don't help without at least the symbol table for the
executable, and it's much easier to analyze them on the machine where
they were generated in any case (especially since many of our tools
actually run XEmacs code to produce Lisp output etc).

Can you provide a backtrace so that we can see where it crashed?  You
may be able to get a Lisp backtrace as well with the lbt command
(provided by .gdbinit).
