As for as octave-stk is concerned, this is a minor failure that does not affect the correct behaviour of the package. You can comment out the test or mark it as expected failure.Thanks for your feedback, I disabled the test in octave-stk.
FYI, the regression in Octave 7 that was creating a test failure
in octave-stk has been fixed upstream, on the stable branch (https://savannah.gnu.org/bugs/?62329).
