--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
```
template<typename _Tp>
_Tp declval();

template <class _Ty>
using t = decltype(declval<_Ty&>().~_Ty());

template <class _Ty, class T1 = t<_Ty>>
void f(int);
template <class _Ty>
int f(long);

int tt = f<int&>(0);
```
