我正在调试的应用程序只有在发布配置下构建时才会崩溃。更令人惊讶的是它在苹果背景队列中崩溃了。看看这个：
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x000000000000defe
Crashed Thread: 9
和此：
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
任何人都可以给我一个提示吗？什么可能导致这样的崩溃？
