------- Comment #1 from rguenth at gcc dot gnu dot org 2005-12-21 12:22 ------- Note that this may be INVALID if we want to treat pointer overflow as undefined, as the std doesn't talk about pointer overflow at all.
Using proper (unsigned) integer types for this kind of arithmetic is recommended anyway. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25512
