I added some new operation-handling in my app, and it's now crashing quite frequently in background threads with EXC_BAD_ACCESS and this:
1 Foundation 0x306cdd46 -[NSObject(NSKeyValueObservingPrivate) _changeValueForKey:key:key:usingBlock:] + 438 2 Foundation 0x306cdb84 -[NSObject(NSKeyValueObservingPrivate) _changeValueForKey:usingBlock:] + 24 3 Foundation 0x30752260 ____NSOQDelayedFinishOperations_block_invoke_0 + 84 4 Foundation 0x306cdd46 -[NSObject(NSKeyValueObservingPrivate) _changeValueForKey:key:key:usingBlock:] + 438 5 Foundation 0x306cdb84 -[NSObject(NSKeyValueObservingPrivate) _changeValueForKey:usingBlock:] + 24 6 Foundation 0x307521d4 __NSOQDelayedFinishOperations + 128 7 libdispatch.dylib 0x377df9a2 _dispatch_after_timer_callback + 6 8 libdispatch.dylib 0x377e2252 _dispatch_source_invoke + 510 9 libdispatch.dylib 0x377dfb1e _dispatch_queue_invoke$VARIANT$up + 42 10 libdispatch.dylib 0x377e0784 _dispatch_worker_thread2 + 208 11 libsystem_c.dylib 0x346afdf4 _pthread_wqthread + 288 12 libsystem_c.dylib 0x346afcc8 start_wqthread + 0 The thing is, I'm not updating the UI from this background thread, and I don't see any difference between the new code and essentially identical code that has been running crash-free for months. Is there some other common pitfall here (aside from updating the UI in a background thread) that could be responsible? Thanks for any ideas.
