[vtk-developers] LONG backtrace of segfault in Geovis-TestCoincidentGeoGraphRepresentation2D on bubbles OSMesa build

[David Cole]

Why are we doing this? (line 328 and surroundings of Views/vtkRenderView.cxx)

  if (caller == this->GetInteractor() && eventId == vtkCommand::RenderEvent)
    {
    vtkDebugMacro(<< "interactor causing a render event.");
    this->Render();
    }

We should not call Render in repsonse to a RenderEvent unless we are
100% confident that calling Render will not throw another RenderEvent.
I think this is one of the definitions of an infinite loop. Am I
missing something?
