From release: Xemacs 21.5 (beta27) "fiddleheads" [Lucid] (i686-pc-linux) of Tue Jul 25 2006
 
Fatal error: assertion failed, file signal.c, line 730, QUIT called from within
redisplay without being properly wrapped
 
Fatal error (6).
 
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).
 
*Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely
to be able to analyze the problem.  Locate the core file produced as a result
of this crash (often called `core' or `core.<process-id>', and located in
the directory in which you started XEmacs or your home directory), and type
 
  gdb /usr/local/bin/xemacs core
 
then type `where' at the debugger prompt.  No GDB on your system?  You may
have DBX, or XDB, or SDB.  (Ask your system administrator if you need help.)
If no core file was produced, enable them (often with `ulimit -c unlimited')
in case of future recurrance of the crash.
 
Lisp backtrace follows:
