[Octave-bug-tracker] [bug #63384] Error for "inv(NaN)" with LAPACK 3.11.0

[Markus Mützel]

Follow-up Comment #23, bug #63384 (project octave):

Is it possible to stop in Fortran code with a debugger?
If it is, what is the value of AINVNM in both versions of LAPACK in
dgecon.f:250?
https://github.com/Reference-LAPACK/lapack/blob/master/SRC/dgecon.f#L250

Maybe, it was finite before and is NaN in the newer version?

Anyway, we could probably add a short-hand in our code if `anorm` is NaN here
(and not proceed to use LAPACK at all):
