--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to David Krauss from comment #10) > I made a clean build of r220825, and it succeeded. Then I downgraded to > r220000, and it produced similar link errors, although not in type_info. This is rather vague, did you do a clean build of r220000? If not, there's nothing we need to fix here, it's user error.
