I have a
vtu file containing a mesh composed of hexahedrons and polyhedrons. When I try to use
vtkGeometryFilter() on this data it results in segmentation fault. I have included a MWE via python that can be downloaded form (http://dl.free.fr/jstNegHHL).
I know that the
vtkGeometryFilter() has been threaded, so when I set number of threads to 1, 2, or 3 using
OMP_NUM_THREADS I do not face any problem, but when the number of threads is set to more than 4, I get segmentation fault. This behavior can be replicated on CentOS7 and Fedora 30 machines using the recent VTK release that ships with ParaView 5.9.
Have I stumbled upon a potential bug ?
PS: I was not able to attach a file as I am a new user to this forum (“Sorry, new users can not upload attachments.”), hence the vtu and python were uploaded to http://dl.free.fr/jstNegHHL
