First, make sure you are using fsf gcc 3.3.3 and not the derivative shipped by your distro maker (it seems all distros hand-roll their own gcc derivative ... don't ask me why.) If you can still reproduce with fsf gcc, I think you should report this as a bug. There's a similar bug reported against 3.4-branch: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13134 but it doesn't mention 3.3.3 .
