1. emacs -Q
2. M-x find-file /home/ldionmarcil/Documents/bugreportemacs/_mixins.scssc RET
3. Emacs segfault

Attachment: backtrace.txt
Description: Backtrace

Attachment: _mixins.scssc
Description: File crashing emacs

The .gitinit does not want to play nice with my gdb so I am unable to
get xbacktrace working. I'm also attaching the file in question that
caused the segfault. See mixins.scssc.

OK, I back-ported it to the emacs-24 branch, and I'm closing this bug.
