[Paraview-developers] Cray Dashboard Failure Diagnosis

[Biddiscombe, John A.]

Pat,

> the segfaults are from tests that call vtkRenderWindowInteractor::New(), causing an infinite loop inside vtkGraphicsFactory.cxx

This is a good theory, Can anyone who is not on holiday :) confirm if any of these tests (the passing ones) instantiate interactors (list of Widget test results at end)

Burlen :

>Can you run one of the tests in a debugger and see specifically where it segfaults? I'm sure that will give you the clue you're after. I guess this is obvious so maybe there is a reason you haven't done it.



Quite right. For reasons unknown to me, I don't get any symbol information and gdb tells me nothing. I've been asking around to see why my build has no debug info, but so far I'm clueless.



Anyone :

Important observation, looking at various outputs, I noticed that for example, CellLocator test does this



76: Test command: /users/biddisco/build/paraview/bin/GraphicsCxxTests CellLocator -D /apps/sandbox/VTKData -T /users/biddisco/build/paraview/VTK/Testing/Temporary -V Baseline/Graphics/CellLocator.png

76: Test timeout computed to be: 1500

76: Passed: a total of 9802 ray-sphere intersections detected.

1/1 Test #76: CellLocator ......................***Exception: SegFault  0.23 sec



It actually does the test OK, but fails on exit. So now I'm lookingat cleanup code etc.
