Well, this doesn't seem to be a GCC bug - but if someone can propose a work-around, that's fine (I just have doubts that a fix includes will be enough). > And if it is a fix from the Apple side, how will I know that an update > contains the desired fix? We will only be able to figure that out by testing it - of course, if you file a radar about it - then presumably that would be updated when it's fixed.
