Fatal error.

Your files have been auto-saved.
Use `M-x recover-session' to recover them.

Your version of XEmacs was distributed with a PROBLEMS file that may describe
your crash, and with luck a workaround.  Please check it first, but do report
the crash anyway.

Please report this bug by invoking M-x report-emacs-bug, or by selecting
`Send Bug Report' from the Help menu.  If that won't work, send ordinary
email to `xemacs-beta@xemacs.org'.  *MAKE SURE* to include this entire
output from this crash, especially including the Lisp backtrace, as well as
the XEmacs configuration from M-x describe-installation (or equivalently,
the file `Installation' in the top of the build tree).

If you are fortunate enough to have some sort of debugging aid installed
on your system, for example Visual C++, and you can get a C stack backtrace,
*please* include it, as it will make our life far easier.


Lisp backtrace follows:
