--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-12-14 07:22:59 UTC --- This one segfaults right away for me, even with trunk as of today (though, I've preprocessed it with 4.6.2 g++ -E -std=c++0x), so this is the more important ice-on-invalid-code category rather than just error-recovery.
