If your distro provides a corresponding debug package for the xemacs
binary, it would help if you could install it and get file name and
line number information.  Assuming we can reproduce it, we can get
that easily enough, but there's no guarantee.

Aidan fixed (or at least diagnosed) a bug with symptoms something like
this; I think there is a fix in 21.4.20.  I'll check later.

This is suicidal, at least if there are any compiled libraries in
there.  The GNU Emacs bytecompiler now produces bytecode that is
capable of crashing XEmacs, at worst.  You really want to avoid having
GNU-compiled byte code anywhere near XEmacs.

(This doesn't have anything to do with the crash you're seeing, I
believe.)
