In any case, what would cause an application built with the debug configuration to not exhibit this bug at all while the same application built with the release configuration will crash randomly?
Changes in the layout of code or the stack. In particular, if you have bugs involving uninitialized variables or stack smashers, the behavior may change if such layout changes.
If you haven't already, run the static analyzer (Build and Analyze) on your code. Also, turn on as many compiler warnings as are useful and fix them. Note that some warnings require that optimizations be turned on to be effective, because they rely on data-flow analysis and the like that's only performed during optimization.
Good luck, Ken
Ken, Just an update. I ran the analyzer and it found out a variable that was not initialized but that I was using later to check for nil value. I did recompile with change and my app has been running for well over 2 hours now without a single crash.
