It doesn't actually seem to cause Travis to fail. Might be related to #3782

Travis does not notice because it assumes tests pass unless exceptions are raised and running parallel it just loses a process and keeps going...

This seems to occur only under python 3. It is presumably caused by the switch to using the new numpy::array_view classes (PR #3744). I am looking into it.
Is there any way we can get travis to catch these occasions and report them as test failures?
Fix for matplotlib#3789, segfault in _tri
Merge pull request #3797 from ianthomas23/3789_segfault

This should be fixed.
