Yes, this is a duplicate of #29606. Sorry for not finding that.
Attached is a new patch (based on Alexey's suggestion) that now should
apply cleanly to bzr trunk. The previous was against v1.15. It also
includes the tested case in #29606 in test_sf.c.
For completeness, while the case in #29606 is correct (6j to be 0 as
half-integer with integer cannot couple to integer), I think there were
a typo in the report: jc=21 should be jd=22, giving
abs(1-21.5)=20.5 <= 22 <= 22.5.
instead of
abs(1-21.5)=20.5 <= 21 <= 22.5.
Cheers,
Håkan
