--- Comment #7 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Sorry for the breakage. Looks like I missed walking DECL_ARGUMENTS of a
FUNCTION_DECL relies on this; the following patch fixes the minimal reproducers
of both this and PR 121935, but I'll see if there's any more checking I can do.
Otherwise I guess I'll revert the last patch and see if there's another
approach.
