QHull issue from 2019.1 (7.3.2)
The BVTreeFactory test is failing from QHull 2019.1 (7.3.2). It has been tested that 7.3.1 works as expected.
It is unknown if the Q-hulls are still valid under 7.3.2 (it could be that it is just some ordering issue). The tests for QHull should be extended to capture the failure (if possible), as BVTreeFactory is too high-level for debugging.
