From: Roland Winkler <roland.winkler <at> physik.uni-erlangen.de> To: bug-gnu-emacs <at> gnu.org Subject: 23.2; emacs crashes when reverting a file Date: Tue, 11 May 2010 18:28:10 -0500I'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.
