The following tests FAILED:
54 - redux_7 (Failed)
238 - stable_norm_5 (Failed)
431 - umeyama_2 (Failed)
500 - matrix_exponential_1 (Failed)
redux_7 seems to be CLang freezing while trying to compile it.
stable_norm_5 was a bug in the unit test, now fixed
umeyama was a bug in the test, now fixed.
and matrix_exponential was also a test that needed tuning.
