--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah, I'd prefer both patches (of course just a single testcase).  For the
decomp, there is really nothing wrong with the artificial var's type, and there
could be other places lurking which are upset about error_mark_node type on
decls.
