This is not a memory leak issue, there is some error causing your application to crash.

In XCode, run the app in debug mode, so when it crashes, before terminating, it will let you debug (with gdb, on the console). Try the command "bt" (short for backtrace), which will show the stack trace of where the crash happen.
