This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.
Please describe as succinctly as possible:
- What happened.
- What you thought should have happened.
- Precisely what you were doing at the time.
Please also include any C or lisp back-traces that you may have.
================================================================
Dear Bug Team!
Here's a way to crash xemacs if you write broken lisp (I know why it's
broken and how to fix it):
