Follow-up Comment #4, bug #34850 (project octave):

I know nothing of Octave internals, but it seems to me that the most logical
way would be to propagate the "lower" choice down to LAPACK; this also saves
the transpose (which takes time). 
I have trouble now looking at the patch something is worng with the
connection, but about a hour ago I got a glimpse, and I remember you are
calling X.transpose() for complex data; in that case you want to have the
conjugate transpose to feed ZPOTRF.
