macOS 12.3 This is a rather rare bug (never seen before):
Thread 12 Crashed:: Dispatch queue: เสือ :: NSOperation 0x61800184fbd0 (QOS: UTILITY) 0 libsystem_kernel.dylib 0x00007fffb3d65dd6 __pthread_kill + 10 1 libsystem_pthread.dylib 0x00007fffb3e51787 pthread_kill + 90 2 libsystem_c.dylib 0x00007fffb3ccb420 abort + 129 3 libc++abi.dylib 0x00007fffb282885a abort_message + 266 4 libc++abi.dylib 0x00007fffb284dc4f default_terminate_handler() + 267 5 libobjc.A.dylib 0x00007fffb3357b8e _objc_terminate() + 103 6 libc++abi.dylib 0x00007fffb284ad69 std::__terminate(void (*)()) + 8 7 libc++abi.dylib 0x00007fffb284ade3 std::terminate() + 51 8 libdispatch.dylib 0x00007fffb3c010cc _dispatch_client_callout + 28 9 libdispatch.dylib 0x00007fffb3c17ae5 _dispatch_queue_serial_drain + 896 10 libdispatch.dylib 0x00007fffb3c09cd9 _dispatch_queue_invoke + 1046 11 libdispatch.dylib 0x00007fffb3c02e70 _dispatch_root_queue_drain + 476 12 libdispatch.dylib 0x00007fffb3c02c47 _dispatch_worker_thread3 + 99 13 libsystem_pthread.dylib 0x00007fffb3e4e712 _pthread_wqthread + 1299 14 libsystem_pthread.dylib 0x00007fffb3e4e1ed start_wqthread + 13 The NSOperationQueue named “ เสือ" is created at the start of the app thusly: @interface EchoStreamServer() @property (strong) NSOperationQueue *commandOperationQueue; @end @implementation EchoStreamServer - (instancetype)initWithInputStream: (NSInputStream *)istr outputStream:(NSOutputStream *)ostr owner: (id <EchoProtocol>)oo security: securityThing service: (NSNetService *)svice; { self = [ super initWithInputStream: istr …. ]; if ( self == nil ) return nil; _commandOperationQueue = [ [ NSOperationQueue alloc ] init ]; _commandOperationQueue.name = @"เสือ"; _commandOperationQueue.qualityOfService = [ oo echoQualityOfService ]; // NSQualityOfServiceUtility return self; } // this is called as answer to a request from a client: - (void)sendToOwnerObject: obb seqNbr: (NSUInteger)seqNbr; { if ( self.owner == nil )…. // error NSBlockOperation *echoOperation = [ [ NSBlockOperation alloc ] init ]; __weak NSBlockOperation *weakBo = echoOperation; [ echoOperation addExecutionBlock: ^void(void) { [ self.owner echoObject: obb seqNbr: seqNbr from: self operation: weakBo ]; } ]; [ self.commandOperationQueue addOperation: echoOperation ]; } // this probably is never called: - (void)cancelEchoOperations: (BOOL)explicit; { [ self.commandOperationQueue cancelAllOperations ]; … } Any ideas how to debug this?
