Interpretation of the return line when a failure occurs on the device, but not in the simulator

My application crashes when I run it on my iPhone 4, but this does not happen when I run it on a simulator. I imagine something that I use more memory than allowed.

I have no idea about the error. The error is only (lldb), and when I click bt, I get the code below ...

I would be very grateful if someone threw me some light on how to begin to understand this error message, because for me it looks like Chinese (and, of course, I'm not Chinese)
