App Crashing

My app works fine but depending on something (that I still don't know), the app suddenly crashes.

The only message error I have is: Thread 1: EXC_BAD_ACCESS (code=1, address=0x5c)

How can I debug it and know exactly why this is happening ?

Thank you,

Hard to say something sure with just shown EXC_BAD_ACCESS. Check all the info shown in Xcode, stack traces, debug prints and logs, all such things.
