vtkTriangleFilter filter segfaults with certain geometry
Please see parent ticket for context if needed.
my example unit tests are here:
https://github.com/Joel-Mckay/gravity_align_3d
and local copy of the files: CMakeLists.txt gravity_align_3d.cxx
the meshlabs repaired obj that seems to still break things: 3D.tar.gz
uncomment line 51 in gravity_align_3d.cxx
#define CLEAN_OBJ_POLY_DATA 1
Then run test2.sh to replicate issue with meshlab file. Note bug1.sh is likely another issue with museums data.
