Subject: bug#17753: Cygwin emacs-X11 core dump
Date: Fri, 4 Jul 2014 23:21:54 +0200	[thread overview]
Message-ID: <21431.6898.745604.392984@wombat.mininet> (raw)
In-Reply-To: <21398.11604.630991.757383@wombat.mininet>

Hi again,

today I witnessed the second coredump of Cygwin emacs-x11.exe (64
bit). The setup is the same as reported previously in this thread. The
backtraces have some striking similarities:

Thread 1 looks a bit different to me this time, but the remaining
threads look like copies of the first crash.

This time the crash occurred while I was publishing my planner pages
to xhtml.

I'm aware that you won't be able to do much unless I provide a recipe
to reproduce the bug. This looks impossible to me. The second crash
occurred roughly 4 weeks after the first one. I run Cygwin Emacs
roughly 10 h a day, so I experience one crash in like 200 h. Also, as
I have to use Emacs productively at my dayjob, I won't be able to run
emacs-x11 -Q for weeks in order to see if any of my customizations
interfere.

Please let me know if I can pull any additional knowledge from these
coredumps.


regards,
Markus
