Segfaults? I have not seen something like that. Would you mind reporting such issue?

Don’t have the dataset in hand. But definitely recall such errors when developing a filter.

Will report when I see one!

Segfaults usually originate from out of memory accesses so, if you feed garbage to an algorithm that does not expect garbage then you are probably gonna have a problem. We could have an output consistency test at least memory access wise, but that’s gonna be an overhead for sure.

Yep, in the reported stack trace, the access violation originates from `vtkGeometryRepresentationWithFaces`. Those sanity checks you suggested would definitely help in both situations (readers and filters)
