Follow-up Comment #27, bug #56952 (project octave):

OK.  The crash recorded in the stack trace from comment #25 looks much the
same as the one I've seen before with the GUI thread calling
QtHandles::qt_graphics_toolkit::create_object through a signal/slot connection
but this time, the interpreter thread hasn't finished executing the --eval
option code.  So maybe this is due to incorrect locking/unlocking of handle
graphics objects between the GUI and interpreter threads?
