What we need to diagnose a crash, usually, is a C backtrace.  If you know
how to force XEmacs to crash, you can usually get the backtrace by starting
XEmacs in a debugger.  On systems with gdb, something like

$ gdb /usr/local/bin/xemacs
(gdb) run
<some message about XEmacs crashing>
(gdb) bt
<long text of backtrace>

Then save the terminal output to a file, and attach it to your report.
The backtrace will usually run off the screen.  If that makes it difficult
to capture all the output, you can run gdb as

$ gdb /usr/local/bin/xemacs 2>&1 | tee crash.log

which will save everything that gdb outputs to the file crash.log.

Good luck!
