Your comparison function is bogus.

You return (in essence) a < b.

Which is a bool, so converts to 0 or 1 (false, true)

Per spec, a result of 0 means that the two values are the same, so if we end do compare(3,1) we will get a result of 0 (3 and 1 are the same value for the purposes of sorting) but if we do compare(1,3) we will get a result of 1 (1 is greater than 3, for the purpose of sorting).

Hence the results are inconsistent and we can't guarantee anything sensible will come out the other end.
