xemacs core dumps, possible GC related bug?
In XEmacs 21.2 (beta45) "Thelxepeia" [Lucid] (sparc-sun-solaris2.6, Mule) of
Thu Mar 15 2001 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:
======================================================================
Create a dummy file, such as foo.scm:
----------------------------
;; -*- mode: bee; -*-
;;
----------------------------
install bee mode under site-packages/lisp (it's a 300kb tgz file, so I can
send it when needed)
$ xemacs -q
M-x load-library bee-mode
M-x find-file foo.scm
M-x rmail (or vm)
Crashes every time.
SunOS foobar 5.6 Generic_105181-11 sun4u sparc SUNW,Ultra-60
