Contour segmentation fault

[FrankFrank9]

Describe the bug, what's wrong, and what you expected.

Hello,

I noticed a strange behaviour: if I run the script below (to make the contour) multiple times sometimes it segfaults other works correctly (on average it works 1 time out of 5). It seems to be related to my file only which is quite big (30 million of points for reference)

Any idea?

Steps to reproduce the bug.

soln = pv.get_reader("./file.hdf").read()
qcontour = soln.contour(
    isosurfaces=np.array([100]),
    scalars="QCriterion",
)

qcontour.plot()

Thanks for reporting. To determine the cause, we need the read file where the error occurs and the error message.
