OK, I guess I have a clue then: this object is manually built,
probably with a wrong vertex numbering on one face.

There is -g in the "Debug" mode, but probably it doesn't help because
the main display operations are called from the GLUT framework.

You give the routines' addresses to GLUT:
    ReshapeFunc(      Window_Resize'Address        );
    DisplayFunc(      Main_operations'Address      );
    IdleFunc(         Main_operations'Address      );
    GLUT.Devices.Initialize;

Then, you start the game:
  GLUT.MainLoop;  -- Let's rock !

With all that, the traceback probably cannot go further than the
latter instruction.
