[Andrew, we talked about this a few months ago. Just making sure we're on the same page so I can push it. Also, a heads-up for Jakub.] The == operator for ranges signifies that two ranges contain the same thing, not that they are ultimately equal. So [2,4] == [2,4], even though one may be a 2 and the other may be a 3. Similarly with two VARYING ranges. There is an oversight in frange::operator== where we are returning false for two identical NANs. This is causing us to never cache NANs in sbr_sparse_bitmap::set_bb_range.
yes, this is correct. Andrew
