A user reported a non-reproducible crash in the heartbeat thread while my app was showing an alert window with a progress indicator. In list archives I've read that this may be due to (a) a memory management bug in my code or (b) a bug in Mac OS X. Both of these seem unlikely since I've been shipping that code for 5 years, and the bug in Mac OS X was back in 2004.
Any ideas?
