Subject: bug#2265: Core dump with "Fatal error (6).Abort" message
Date: Tue, 10 Feb 2009 09:04:00 +0000

Hello.

I'm on Fedora 10, 64 bit. I run Emacs from the HEAD of CVS. Emacs
started to dump core after I started using multi-mode.el
(http://www.loveshack.ukfsn.org/emacs/multi-mode.el) to edit using both
lisp-mode.el and tex-mode.el in the same buffer. When it crashes, it
displays the message "Fatal error (6).Abort". If I don't activate
multi-mode.el, everything works very reliably.

The crash happens randomly, while I'm editing, simply moving in the 
buffer, etc.

This happens in all the revisions I tried in the last two weeks. I did 
not try Emacs 22.

Here is the output of "uname -a"

and here is the backtrace:
