From: David Engster <deng <at> randomsample.de> To: 6579 <at> debbugs.gnu.org Subject: bug#6579: 23.2; (require 'dbus) without dbus being available makes Emacs unresponsive, maxing out CPU and eating memory Date: Wed, 07 Jul 2010 14:20:46 +0200
This was observed on GNU/Linux (Archlinux), but I also witnessed this
under OS X.
* Stop dbus or do not start it in the first place.
* emacs -Q
* evaluate (require 'dbus) in the scratch buffer
Emacs now consumes 100% CPU and is quickly eating memory until there is
no more. Pressing C-g (or any other key) doesn't have any effect.
Attaching gdb to Emacs in this situation usually shows different
backtraces; here is one example:
