I sympathize. It can be very hard to debug these sorts of things. A couple of things I would try: 1) Examine the registers for the stack frame of the objc_msgSend_vtable5() call to see if you can figure out what message was being sent and possibly its arguments. <http://sealiesoftware.com/blog/archive/2008/09/22/objc_explain_So_you_crashed_in_objc_msgSend.html> 2) Run under the Zombies instrument, which collects history for object addresses. At the crash point, try to identify the address of the object being messaged (see above) and then examine its history to figure what that is/was, where it was allocated, and what might have happened to it. You can also use MallocStackLoggingNoCompact to collect the history without the Zombies instrument, if that's easier. Either use the malloc_history command or gdb's "info malloc-history" command.
