--- Comment #15 from Matthieu Brucher <matthieu.brucher at gmail dot com> --- Thanks, finally something relevant, yes it's a bug that can be easilly checked by gcc and that GCC can easilly warn about. (lowering the bar here). Yes, the user should chase the bug because they screwep on a monumental level. But why can't gcc warn that the user is about to do something stupid or tell them that the comparison is always true? Of course, if there is a warning level that already does that, my comment is moot (although making it a higher level warning may help).
