Follow-up Comment #16, bug #56952 (project octave):

I'm also seeing a crash at exit when executing a script file (related to bug
#56952, it seems) that also appears to be "fixed" by not connecting
m_interpreter_qobj->octave_finished_signal to m_main_thread->quit and making
the call to m_main_thread->quit directly in the
base_qobject::handle_octave_finished function.

Printing "\n" to stderr doesn't seem to be needed.  What does that do on
MacOS?  Is it needed to actually print the newline at exit?

In any case, it looks like there is some general call sequence and threading
issue here.  I pushed the following changeset:
