Doesn't this risk overflow warnings on some platforms?

I'm inclined to say "apparently not" (:grin:) since all CI builds went fine. The only problem could be if the length really is larger than 31 bits since then the typecast will lose bits. But these cases should never have that large of a length, and since the printf() code itself only yanks out an int already since before it has not been an issue before either.
