Ensight reader cause segfault using ghost cells
I'm unsure if this bug belong in the Paraview or VTK bugtracker, I can re-file it in the VTK bug tracker if needed.
Using the ghost cell feature of the Ensight file format, which is analogue to the similar feature in VTK/Paraview, Paraview segfault/crash. This is happening on recent versions, tested both Paraview 5.5.2 and 5.7.0.
If the 'ghost_flags' block of the Ensight geo-file is removed, Paraview is able to open the case. The attached case consist of three parts, and the corresponding 'ghost_flags' blocks of the three parts start at line 121, 46894 and 93667 in newcase.geo. The 'ens_checker' tool provided together with Ensight to validate the Ensight Gold format give no warnings on the attached case.
Ideally Paraview/VTK should read the content of the 'ghost_flags' and put it in a vtkGhostType-array for proper rendering.
The attached files demonstrate the problem.
