--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is the proper testcase:
```
#include <typeinfo>

struct S {
      int m;
      static void f_sizeof() { (void) sizeof(m); }
      static void f_typeid() { (void) typeid(decltype(m)); }

      struct N {
      int m;
      static void f_sizeof() { (void) sizeof(m); }
      static void f_typeid() { (void) typeid(decltype(m)); }
      };

      template <class T> class C {
      public:
      int m;
      static void f_sizeof() { (void) sizeof(m); }
      static void f_typeid() { (void) typeid(decltype(m)); }
      };
  } s;
static void f_typeid() { (void) typeid(S::m); }
```
