Follow-up Comment #7, bug #68254 (group octave):

Ok, this was my fault.  Adding just a bug number to a BIST test marks it as a
known failure.  I needed to add an asterisk to mark it as a resolved bug so
that a failure would then be counted as a regression.

I did that and now everything is working as expected.
