------- Comment #1 from rguenth at gcc dot gnu dot org 2006-12-09 11:02 -------
This is because for the first line
(*((char *)(p) + 0) = (char) ((dat)) & 0xff)
we do the len + 1 in unsigned char type (we recognize x & 0xff as a
cast to unsigned char). So we have two additions and cannot figure out
in the end that one is redundant.
(we might have a dup for this)
