[Message part 1 (text/plain, inline)]

Hi,

when I recently upgraded to OS X 10.8, my Emacs started crashing when hitting the Zoom button (+) of the window / frame. This does not happen all the time, but very often. I use the builds from emacsformacosx.com. I have attached the OS X crash report for this situation.

The crash does not happen when I run emacs with empty init.el. My init.el loads quite a bit of stuff (cedet, ecb etc). But I cannot determine a single point where it starts to go bad. I guess there might be some feature in Emacs that triggers the crash that is used by one ore more of the packages I load. Maybe the attached backtrace helps.

All the best,

Arne

It is definitly something in you startup file, as it crashes when running window-configuration-change hook.

Start emacs and check the value of that variable.  It should give some clue as to which package is the culprit.

Done. And by the way, I also tested with Emacs 24.2 from MacPorts. Has the same crash. Here is the value of the variable:

A quick test of doing "M-x linum-mode" after startup allowed me to zoom / maximize without crash. But I will have to do a bit more testing if linum-mode indeed triggers the behaviour.

Cheers,

Arne

Actually there is a bug here.  I fixed it in the trunk.
