Question

A user has just submitted a bug report to me, saying that my app crashed. The user also attached a throw call stack.

The part which seems to have caused the problem is:

       3   My App                0x000000010d005483 My App + 17539

Is there a way to translate that address and/or the + 17539 to a line number in my code?

Keep in mind, I wasn’t able to reproduce the bug on my machine, so I can’t just build it in debug mode.

Check out this Tech note from Apple.

… This trace is similar to what you would see when stopping execution in the debugger, except that you are not given the method or function names, known as symbols. Instead, you have hexadecimal addresses and executable code – your application or system frameworks – to which they refer. You need to map these addresses to symbols. Unlike crash logs from Mac OS X, iPhone OS logs do not contain symbol information when they’re written out. You have to symbolicate iPhone OS logs before you can analyze them.
