From: Brad Town <brad <at> bradtown.com> To: Jan Djärv <jan.h.d <at> swipnet.se> Cc: 11081 <at> debbugs.gnu.org Subject: bug#11081: 24.0.94; "emacsclient --create-frame" occasionally crashes daemon or causes daemon to hang Date: Thu, 29 Mar 2012 09:27:54 -0700
When I was using GDB, I only saw the hang, and that's what I attempted
to capture. If you have a quick suggestion as to how I might be able
to get better information for you, let me know.
Another interesting item: The problem goes away when I rebuild with
the GTK toolkit. Unfortunately, I use Emacs as a daemon, and the Lucid
toolkit is recommended for that setup.
