k can be < 0, but not j. In both cases, it turns out. But interesting
that it only shows up in 64 bit?
Also, getting the types "right" is all very well, but this is a great
example where it doesn't really work unless you also do range checking
(e.g. a size_t with top bit set is not going to work properly when
converted to a ssize_t).
