Summary0012647: Segfault when reading parallel image data
DescriptionRan across this in PV 3.8.1 and 3.10.1, turned out to be a bug in VTK.

I originally converted a set of DICOM slices into a .pvti + 16*.vti dataset, using GDCM's VTK DICOM reader and the regular VTK parallel .vti writer class.

The resulting dataset can't be read back in as it causes a segfault. See the attached two scripts. The gen.py script generates a dataset (similar to the one originally causing the problem). The read.py script reads it back in, but segfaults:

paulm@v41-8:~/projects/acta_scans/CT-dataset/dicom_3/dicom_3/pv$ ./read.py
Segmentation fault (core dumped)

Bloody hell, guys. It turns out I reported the exact same issue almost a year ago in 0011607, which has since expired :-/
