Strange stack trace in crash on thread
I am getting a very strange and very occasional, random crash on a secondary thread. I don't know what to make of the stack trace. Any ideas as to what could be happening here would be appreciated please?
This occurs when drawing strings and images to a graphic context on a background thread.
Solution
Finally got it - this was caused by calling some of NSString's drawing methods to a graphic context on a secondary thread. They are supposed to be thread safe but it is an iOS6 bug. Can be solved by using Core Text or NSAttributedString drawing methods.
