xemacs still core dumps

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 (beta43) "Terspichore" [Lucid] (sparc-sun-solaris2.6, Mule) of Mon Feb 5 2001 on betty configured using `configure --with-mule --with-clash-detection' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I had posted this bug in xemacs 21.2.38 and it still core dumps. Looks like a GC related bug. Running bee-mode (a bigloo/scheme programming mode), I get a core dump. Can't tell if it's bee-mode itself, or possibly a font-lock problem. It's repeatable. Create a dummy file, such as foo.scm: ---------------------------- ;; -*- mode: bee; -*- ;; ---------------------------- install bee mode, then run xemacs. $ xemacs -q M-x load-library bee-mode M-x find-file foo.scm M-x rmail (or vm) I can post a copy of bee-mode if you like (about 158kb, gzipped). $ gdb xemacs GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
