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.
In XEmacs 21.2 (beta38) "Peisino,Ak(B" [Lucid] (sparc-sun-solaris2.6, Mule)
of Mon Dec 11 2000 on atom
configured using `configure --with-mule --with-clash-detection'
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Running bee-mode (a bigloo/scheme programming mode), I get a core
dump. No clue why, but it's been like this for the past several
versions. Can't tell if it's bee-mode itself, or possibly a
font-lock problem.

Do you have a recipe to reproduce it? It looks like a GC
bug and it's really hard to track down it without a
reproducible recipe.
I have similar crash under TTY with glyphs on modeline.
Does bee-mode do similar things?

I was afraid it might be a GC bug.
I have similar crash under TTY with glyphs on modeline.

Yes, it's repeatable. Create a dummy file, such as foo.scm:
----------------------------
;; -*- mode: bee; -*-
;;
----------------------------
install bee mode under site-packages/lisp (attachment enclosed)
$ xemacs -q
M-x load-library bee-mode
M-x find-file foo.scm
M-x rmail (or vm)
Crashes every time.

This article reminds me about my XEmacs crash related to TTY, glyphs
and GC. Once I reported the crash several(?) months ago. The problem
persists until now.
I can always reproduce the crash by the following method:
xemacs -vanilla (on X windows environment)
M-x make-frame-on-tty
M-x hanoi
M-x display-time (using graphical icons)
M-x garbage-collect
**crash**
I can change 'M-x hanoi' with other (possibly heavier) applications.
When I only do
M-x make-frame-on-tty
M-x display-time
M-x garbage-collect
it seldom crash. I guess I need to stir memory to make it crash.
After I read previous discussions about GC crashes, I tried to find
the crashing part using 'always_gc' flag. I turned on 'always_gc'
just before M-x display-time, waited forever, and got the following
stacktrace. I have no idea what I should do next. Any suggestions?
