I get this too.
I didn't a week ago.
In fact, I know it wasn't like this at the beginning of february,
because the new-register allocator branch was from the beginning of
feb, and it didn't have this problem.

I'll tell if it's libstdc++-v3 or g++ in a moment, the new-regalloc-branch
has an up-to-date gcc subdir, but i never merged libstdc++-v3 to HEAD,
so it's still from the beginning of feb.
