I agree it should be resolvable, but I think what's happening is after resolving all the templates:

```
template< class T >
std::complex<T> pow( const std::complex<T>& x, const std::complex<T>& y );
```
and
```
template< class T1, class T2 >
std::complex<std::common_type_t<T1, T2>>
    pow( const std::complex<T1>& x, const std::complex<T2>& y );
 ```

have the same type, since `std::common_type_t<T, T> == T`. I might be wrong and the issue is somewhere else though!
