FWIW, this should be fixed by https://cgit.freedesktop.org/xorg/xserver/commit/?id=9f04fa3babaaabe0ed5bf4aa2563755bc6c45723 . Note that this crash only happens when the X server is already shutting down (or at least resetting for a new generation), so it's kind of a minor issue. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
