I was fooling around trying to arrange that a CCL coding system _not_
to encoding (since most of them will destroy data). I set the encoder
for Windows-1250 to nil, tried to save (C-x C-s) a file that I read
with C-u C-x C-f cp1250.raw RET windows-1250 RET, and boom!
Installation, Lisp bactrace, and C backtrace attached.
Repeatable with xemacs -vanilla

WARNING: ---------------------------------------------------------
WARNING: Compiling in support for runtime error checking.
WARNING: XEmacs will run noticeably more slowly as a result.
WARNING: Error checking is on by default for XEmacs beta releases.
WARNING: ---------------------------------------------------------
Fatal error (11).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
If you have access to the PROBLEMS file that came with your
version of XEmacs, please check to see if your crash is described
there, as there may be a workaround available.
Otherwise, please report this bug by running the send-pr
script included with XEmacs, or selecting `Send Bug Report'
from the help menu.
As a last resort send ordinary email to `crashes(a)xemacs.org'.
*MAKE SURE* to include the information in the command
M-x describe-installation.
If at all possible, *please* try to obtain a C stack backtrace;
it will help us immensely in determining what went wrong.
To do this, locate the core file that was produced as a result
of this crash (it's usually called `core' and is located in the
directory in which you started the editor, or maybe in your home
directory), and type
gdb /home/steve/Projects/XEmacs/Builds/21.2/src/xemacs core
then type `where' when the debugger prompt comes up.
(If you don't have GDB on your system, you might have DBX,
or XDB, or SDB. A similar procedure should work for all of
these. Ask your system administrator if you need more help.)
