Has anyone ever experienced a crash like the one below? It is happening sporadically in the field (I have, I think, 5 crash logs, spread across all 3 major versions of OS X, i.e. 10.4, 10.5 and 10.6) but I have never seen it here. Examination of the object code reveals that NSCarbonMenuImpl+527 is a call to [NSMenu _enableItems].
All I have to work from is the crash log, but I'm as confident as one can ever be that our NSMenu object has not been released or corrupted. It is pretty much static for the life of the app. The only thing we do which might be a bit unusual is to call [NSApplication setMainMenu] whenever the app comes to the front. That's not actually necessary and I plan to change it, but I thought it worth mentioning. Any clues anybody?
