Sorry about the silence; I've recently upgraded to Fedora
Core 3, and haven't seen any crashes or weird behaviour yet
(*knocks wood*). I'll keep an eye on things, and will get
back to you if I manage to reproduce the problems and upgrade
my gdb skills to produce what you requested above.
Ok. Also take a look at the new xemacs-faq recently checked in; I added a
whole lot of info on debugging.
