Follow-up Comment #2, bug #29487 (project octave):

It looks like the reverse issue came up in scipy which is claimed to use
GESDD instead of GESVD and was producing incorrect results. Octave and Matlab
were both cited as producing the correct results compared to scipy:

It looks like scipy plans to make both available and let the user choose
which engine to use:
