Follow-up Comment #18, bug #59628 (project octave):

I have grafted cset http://hg.savannah.gnu.org/hgweb/octave/rev/be61ce9c3126
to the stable branch.

The remaining issue with segfaulting while executing


octave --gui --eval '1+1,exit'


can reliably reproduced when the editor is visible and editor files are opened
through enabling restoring the previous session. A backtrace shows that the
segfault is caused by a signal connection in an interpreter thread in line
2022:


connect (this, SIGNAL (update_breakpoints_signal (const octave_value_list&)),
         this, SLOT (update_breakpoints_handler (const octave_value_list&)),
         Qt::QueuedConnection);
