I have just checked: there is no warning with gcc > 4.2 or 4.1, but 3.3 emits the warning. This is a GCC bug (regression, actually, as you've found out) -- no two ways about it. Although different from the kind Jeff mentioned couple days back -- that was about wising GCC up to false positives and /not/ emitting warnings. But here a genuine problem was not complained about, so this is more serious. Do you plan to open up a bug at gcc.gnu.org/bugzilla/ ?
