While I agree with @jeffknupp's comment in #17063 that we should really be using size_t for these types, this patch switches some size_t that were switched from int in d5c75e8 and not subsequently switched to int64_t in e04d12a or 3171674

This patch seems to fix the issue on 32-bit big-endian, I'm running some tests now to make sure it doesn't break anywhere else.
