Follow-up Comment #1, bug #45295 (project octave):

This is probably related to computing the second derivatives in a surface that
is not smooth enough, due to knot repetitions.

Can you try to reproduce the error in a simpler example? A surface of order 3
(degree 2) with one repeated internal knot should be enough. In the example,
can you also include the points where you evaluate?
