The application i'm currently debugging crashes only when it's built under release configuration. And what is more surprising it crashes in apple background queue. Take a look at this:
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x000000000000defe
Crashed Thread: 9
and this:
Thread 9 name: Dispatch queue: com.apple.root.background-priority
Thread 9 Crashed:

5 libsystem_c.dylib 0x3c1ffa0e _pthread_wqthread + 358
6 libsystem_c.dylib 0x3c1ff8a0 start_wqthread + 4
Can anybody give me a hint? What may cause such a crash?
