"Program exited with status value:5"

Question

I've looked around a good bit and never found a comprehensive list of exit codes for Xcode especially working with iOS.

This question: http://stackoverflow.com/questions/2504512/debuging-to-simulator-crashes-with-exited-with-status-5-unless-i-have-breakpoin simply says I need to restart xcode. But the problem is still there for me.

So whats exit code 5? And is there a comprehensive list of exit codes somewhere?
