We have a semi repeatable crash when slicing a vtm dataset. This can frequently be replicated, but unfortunately, it appears to be somewhat random with regards to when it occurs. It also appears totally random which cells internally show the issue. Here is how to replicate:

• ParaView 5.8.0, or master, builtin server, Linux.
• Load dataset named vtm_only_5888_elements.vtm. Variables don't matter. Apply.
• Although it shouldn't matter, -Z.
• Slice. Origin: 0,0,0. Normal: 0,0,1. Apply. This should crash. If it doesn't, delete the slice and create it again.

It is crashing in void vtkPolyData::ComputeBounds(), at

       for (auto cellId = 0; cellId < numCells; ++cellId)
        {
          cellA[ca]->GetCellAtId(cellId, npts, pts);
          for (ptIdx = 0; ptIdx < npts; ++ptIdx)
          {
>>>>            ptUses[pts[ptIdx]] = 1;
          }
        }

where cellA[ca]->GetCellAtId (3 lines above) is returning pts[ptIdx] == bazillions, which is causing a set fault accessing the ptUsers array.

Directions on getting the dataset will be sent to Utkarsh and Berk.
