--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
I can confirm the testcase from comment#3 on trunk but not the earlier two
(those also not on the branch). So those were different cases now fixed.
Re-confirmed for the comment#3 case, but that eventually looks like a C
frontend issue to me accepting invalid code? We gimplify from
;; Function foo (null)
;; enabled by -tree-original
{
typedef union C unionunion C;
extern int map ();
extern int bar ();
typedef union C unionunion C;
bar ({.e=&a});
}
