[Octave-bug-tracker] [bug #48519] Segfault with Qt plotting when running demos

[Dmitri A. Sergatskov]

Follow-up Comment #37, bug #48519 (project octave):

FWIW i can reproduce Hartmut's results with 


octave:1> demo lighting 5
lighting example 5:
 clf;
 colormap ("default");
 mesh (sombrero ());
 shading flat
 lighting flat
 light ();
 title ("shading flat - lighting flat");
