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!
marking the whole buffer with the Perl script included below (there
isn't much to see in it) and pressing C-M-\
(indent-region-or-balanced-expression) reliably crashes XEmacs; the
stack trace is
(if ... ... ...) (beginning-of-line 2)) (if (fboundp ...) (imenu-progress-message pm 100)
(message nil)))
