Cool, I actually did a search before submitting the bug but I did not find
anything and now I see why. The prior bug description does not mention
std::sort.
BTW, in my case, std::sort is just slower regardless of what is sorted. the
data can either be in sort order or be in reverse sort order. In either case,
the mentioned versions are slower.
