Xcode: debug unexpected iOS app crashes

I'm facing unexpected crashes of my app running on an iPhone 4 with iOS 5.0.1, the app crash without generating any error message nor crash log. I did also enabled zombies and tested with Instruments with no luck... how can I figure out where is the problem? I'm totally stuck :(

ps. I'm using ARC and my app is multi thread (NSOpertations + GCD)

From the breakpoint-menu in Xcode, press the little '+' button at your window bottom left, and add an exception breakpoint. It will give you a heads up if the app throws an exception due to erroneous code.

add some breakpoint before crashing point and add a lot of NSAssert to check your assertion.
