EXC_BAD_ACCESS

My app suddenly crashes exposing this message error: EXC_BAD_ACCESS (code=1, address=0x5c) 

I tried to debug but can't find a solution. I believe using Instruments could be easier to find it. However Instruments has a lot of items. What would be the one responsible for debugging this kind of error I'm having ?

Thank you
