--- 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 = f1(p0, t1); // choses #2
char* p2 = 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?
