--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced down to just:
```
void operate_one(const int) {}

template<typename ...T>
void operate_multi(T... args)
{
    [&]<int idx>()
    {
       ::operate_one(args...[idx]); 
    }.template operator()<0>();
}

int main()
{
    ::operate_multi(0);
}
```

The packed index is not being resolved it seems.
