The trouble seems to be the dynamic cast in this code


bool
patch::properties::get_do_lighting (void) const
{
  gh_manager& gh_mgr
    = octave::__get_gh_manager__ ("patch::properties::get_do_lighting");

  graphics_object go = gh_mgr.get_object (get___myhandle__ ());

  axes::properties& ax_props = dynamic_cast<axes::properties&>
    (go.get_ancestor ("axes").get_properties ());

  return (ax_props.get_num_lights () > 0);
}
