We are transitioning to Octave 11 in Debian and there are now 5 test failures in grp2idx, related to the duration class, the first one being:
***** test
s = [duration(NaN, 0, 0), duration(NaN, 0, 0), duration(NaN, 0, 0)];
[g, gn, gl] = grp2idx (s);
assert (g, [NaN; NaN; NaN]);
assert (gn, cell (0,1));
assert (isequal (gl, duration (NaN (0,3))));
!!!!! test failed
ASSERT errors for: assert (gn,cell (0, 1))
