Follow-up Comment #2, bug #50400 (project octave):
At exit(), octave_qt_link::do_confirm_shutdown() tries to lock a QMutex
(which, since it's constructed before forking, is unusable in the child).
QMutex is initialized at construction, doesn't provide a method for
re-initialization, and has copying disabled. So it can't be made usable again
in the forked child.
What can be done to prevent the child from deadlocking at exit()?
