--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. Slightly reduced:
```
template<typename T1>
struct A1 {
template<typename T2>
struct A2 { T2 t; };
};
void s(double k) {
A1<int>::A2 a(2);
}
```
It looks like the deduction guide is not being generated correctly when the
inner template class is of a templated class. If A1 was not a template, GCC
acecpts the code just fine. that is:
```
struct A1 {
template<typename T2>
struct A2 { T2 t; };
};
void s(double k) {
A1::A2 a(2);
}
```
Works just fine.
