*** This bug has been marked as a duplicate of bug 191062 *** Actually I don't think closing this as dupe is a good idea because I suspect hitting ud2 is just a result of it trying to abort - the real problem here is not understanding how to deal with the mach message. Hi memecode, Thanks for the macOS bug report. This one is already identified and being tracked at bz#406681. Tom Hughes is right that hitting ud2 is the result of an abort -- but it's unrelated to the unhandled MACH_SEND_TRAILER option. Instead, we are tracking a bug on macOS within _dispatch_kq_poll(). *** This bug has been marked as a duplicate of bug 406681 *** |
