I guess it has something to do with
NSExceptionHandlerUncaughtSignalHandler, but I don't know what to do
about this.
This is a known issue, having to do with a signal being generated
inside the NSExceptionHandler handler. NSExceptionHandler signal
handling has never been able to be 100% reliable--actually, due to the
impossibility of knowing the full application state when the signal is
raised, nothing that involves proceeding after a signal raise can be
100% reliable--but this goes beyond that, and causes problems even with
signals that could have been caught. We're working on it.
