[Paraview-developers] Cray Dashboard Failure Diagnosis

[pat marion]

Hi John,

I'm back at the office now and I can confirm that it is
vtkRenderWindowInteractor::New causing the segfaults.  You noted that the
CellLocator test seems to crashes at exit, well if you look at the code it
calls vtkRenderWindowInteractor::New after is does 'cout << 'Passed: a total
of 9802 ray-sphere intersections detected.'

The Widgets tests pass because they use vtkTestingObjectFactory to override
vtkRenderWindowInteractor::New() to instantiate a vtkTestingInteractor.

Here is a temp fix- edit VTK/Rendering/vtkGraphicsFactory.cxx and replace:

    return vtkRenderWindowInteractor::New();

with

    return vtkTestingInteractor::New();

Also add an #include "vtkTestingInteractor.h", then recompile and try your
tests again.  Maybe sometime we'll have time to setup a static, python,
osmesa, no x11 dashboard and fix these tests properly.
