From: Nelson Elhage <nelhage <at> nelhage.com> To: 7358 <at> debbugs.gnu.org Subject: bug#7358: 23.1; Crash involving emacsclient -c and multiple $DISPLAYs Date: Tue, 09 Nov 2010 10:13:36 -0500
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
I have been getting a lot of crashes when I run 'emacs --daemon' and
then connect to it using 'emacsclient -c' with multiple $DISPLAY
values. The crashes usually happen when or shortly after I close a
window started on a different $DISPLAY than the one I started --daemon
in.
I'm sorry I can't be more specific -- the bug happens pretty frequently,
but I haven't been able to produce a completely reliable reproducer. I
managed to catch the crash in gdb, thuogh, so I figured I'd submit the
bug with the backtrace (which looks like it might be informative).
