For those unaware, the Apple guys have added "debug" versions of the STL stuff to gcc (well it's still a patch currently).
I think we're really going to have fun with this one. New file triggers an assertion, it's a bug just waiting to kill us it seems : /usr/local/gcc-cvs/include/c++/3.4/debug/safe_iterator.h:180: error: attempt to dereference a past-the-end iterator.
