I was sitting at the main menu in Maelstrom compiled with SDL 1.3, and it crashed:
Program received signal EXC_BAD_ACCESS, Could not access memory.

A similar crash was reported in Eclipse in Mac OS X 10.7 as well:

The app's delegate has been deallocated while it is still attached to the
application, so Appkit crashes while trying to message it.  Whoever is
responsible for setting the NSApp's delegate in the Eclipse Cocoa port should
clear it when that delegate is deallocated.
