Hello for your information there is a bug in the slicing of vtkPolyHedron that can cause a segfault. It looks very much like your error. It has yet to be corrected. https://gitlab.kitware.com/vtk/vtk/issues/16877
You can already test this "work in progress" branch to see if this fixes your issue : https://gitlab.kitware.com/vtk/vtk/merge_requests/2304 You could of course modify your data to tetrahedron with tetrahedralize filter.
