Some tests in "inv.cc-tst" are failing for the stable branch of Octave with
the default branch of MXE Octave:

Those tests are succeeding for the stable branch of Octave with the release
branch of MXE Octave. So, this is likely a regression with one of the
dependencies that have been updated since the release of Octave 7.

CC'ing John Donoghue because I hope he might have a hunch as to who might be
the "culprit".
