--- Comment #6 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-05-24 14:58:53 UTC --- It seems that we can pull in types via that link that have function-decls in them (methods) that do not have an assembler name set. But we happily enter them into symtab merging and so we ICE. See also PR48437 for a related case. Hohumm.
