Wednesday, Apr 14, 2010 Debugging objc_msgsend
Got a clueless exception caused during objc_msgsend:
#0 0×91610ed7 in objc_msgSend ()
#1 0×01025958 in ?? ()
#2 0×30245c32 in __CFRunLoopDoObservers ()
#3 0×3024503f in CFRunLoopRunSpecific ()
#4 0×30244628 in CFRunLoopRunInMode ()
#5 0×32044c31 in GSEventRunModal ()
#6 0×32044cf6 in GSEventRun ()
#7 0×309021ee in UIApplicationMain ()
#8 0×000025f8 in main (argc=1, argv=0xbffff0c0) at /Users/bill/Source/__my dir__/__my app__/trunk/main.m:14

Did a Google search for objc_msgsend debug. There are quote some resources related to this problem. I found the post in Hamster Emporium particular useful: So you crashed in objc_msgSend(). I am no GDB expert. The GDB commands there are super helpful! Awesome!
