--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Take:
```
template<typename T>
struct A { typedef char* type; };

template<typename T> char* f1(T, char*);  // #1
template<typename T> long* f1(T*, typename A<T>::type*); // #2

char *t;
char **t1;
long* p0;
long *p1 =3D f1(p0, t1); // choses #2
char* p2 =3D f1(p0, t); // choses #1
```
GCC, MSVC, and clang all compile the above.

So is it only an issue with nullptr where it could chose either?=
