I use AudioEngine. In crash reports I see some random EXC_BREAKPOINT crashes with this stacktrace Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000001, 0x00000001896df0e4 Termination Signal: Trace/BPT trap: 5 Termination Reason: Namespace SIGNAL, Code 0x5 Terminating Process: exc handler [12467] Triggered by Thread: 15 Thread 15 Crashed: 0 libdispatch.dylib 0x00000001896df0e4 __DISPATCH_WAIT_FOR_QUEUE__ + 448 (queue.c:1619) 1 libdispatch.dylib 0x00000001896dec74 _dispatch_sync_f_slow + 140 (queue.c:1732) 2 libdispatch.dylib 0x00000001896dec74 _dispatch_sync_f_slow + 140 (queue.c:1732) 3 AVFAudio 0x00000001965b11a8 -[AVAudioEngine dealloc] + 308 (AVAudioEngine.mm:406) 4 Foundation 0x0000000189ce52ac -[NSConcreteNotification dealloc] + 68 (NSNotification.m:206) 5 AVFAudio 0x00000001965b7158 invocation function for block in AVAudioEngineImpl::IOUnitConfigurationChanged() + 292 (AVAudioEngine.mm:1215) 6 libdispatch.dylib 0x00000001896de998 _dispatch_block_async_invoke2 + 104 (queue.c:525) 7 libdispatch.dylib 0x00000001896fb184 _dispatch_client_callout + 16 (object.m:495) 8 libdispatch.dylib 0x00000001896d4e8c _dispatch_continuation_pop$VARIANT$armv81 + 404 (inline_internal.h:2484) 9 libdispatch.dylib 0x00000001896e502c _dispatch_source_invoke$VARIANT$armv81 + 1232 (source.c:568) 10 libdispatch.dylib 0x00000001896d85e0 _dispatch_lane_serial_drain$VARIANT$armv81 + 260 (inline_internal.h:2525) 11 libdispatch.dylib 0x00000001896d9128 _dispatch_lane_invoke$VARIANT$armv81 + 400 (queue.c:3863) 12 libdispatch.dylib 0x00000001896e243c _dispatch_workloop_worker_thread + 576 (queue.c:6445) 13 libsystem_pthread.dylib 0x000000018974ab88 _pthread_wqthread + 276 (pthread.c:2351) 14 libsystem_pthread.dylib 0x000000018974d760 start_wqthread + 8 I can't reproduce this crash and stacktrace doesn't point to my code.
