[Octave-bug-tracker] [bug #61994] Crash on GUI exiting with octave_base_value objects still open.

[Markus Mützel]

Follow-up Comment #13, bug #61994 (project octave):

With hg id e022eab3ea1b, Octave closes without issues with a figure still open
when clicking the "x" in the upper right edge of the main window.
However, when I run the GUI, execute the command from comment #0 and close the
GUI with that "x", Octave exits with:

$ ./run-octave --gui
octave exited with signal 11


The gdb backtrace is:
