--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Seems when we call this 'e' doesn't have a type and we crash:

  if (DECL_P (node))
    {
      attrs[0] =3D DECL_ATTRIBUTES (node);
      attrs[1] =3D TYPE_ATTRIBUTES (TREE_TYPE (node));

I suppose

  if ((code =3D=3D FUNCTION_DECL && !excl->function
       && (!excl->type || !spec->affects_type_identity))
      || (code =3D=3D VAR_DECL && !excl->variable
          && (!excl->type || !spec->affects_type_identity))
      || (((code =3D=3D TYPE_DECL || RECORD_OR_UNION_TYPE_P (node)) &&
!excl->type)))
    return false;

could add || (code !=3D FUNCTION_DECL && code !=3D VAR_DECL && code !=3D TY=
PE_DECL)=
