[vtk-developers] [VTK 0011860]: Crash on vtkUnstructuredGrid::GetCell after DeepCopy of an instance containing polhyedrons

[Hua Yang]

Hi Anthony,

Thank you for reporting this bug. You are right,
vtkUnstructuredGrid::DeepCopy() failed to copy of some data attributes
related to polyhedron cells. The bug is now fixed in
899b6f0be74d6127ff5fd9d1e69a2c584e0d992d

Please verify the bug fix and resolve the issue if things work correctly.

Thanks.

Hua
