If you're trying to accomodate the fact that the loops iterate
always by 2 or 4 bytes at a time, then you will need to allocate
up to "3" bytes of slack space, not just "2".

You need to describe exactly what the precise problem is in your
commit message, or else people might find it difficult to figure
out exactly what the problem is.
