By casting buf to an int you have instructed the compiler NOT to treat
it as a byte.

It is beholden on you the software engineer to ensure whatever you
cast is compatible with what you cast it too. In this case you are
saying that &buf[i] is word aligned, which will be only true for one
in four cases of i. If the compiler aligns the start of buf to a word
bondary which will happen under some cases &buf[0] will be the only
legal cast.
