bug#6177: 23.2; emacs crashes when reverting a file |
|
Date: |
Tue, 11 May 2010 18:28:10 -0500 |
I've encountered a situation, where reverting a file reproducibly
crashes emacs. I do not know much about debugging emacs on this level.
I've reproduced the crash under gdb.
xbacktrace doesn't give any information.
`bt full' gives the info attached below.
I'll be happy to provide more information if someone can give me further hints.
