--- Comment #1 from trashyankes at wp dot pl ---
Another similar case:
```
template<typename... T>
struct F : T...
{
F(int i) : T{i}...
{
}
};
int main() {
F<> z{2}; //warning: parameter 'i' set but not used
[-Wunused-but-set-parameter]
}
```

I think in case when variadic list is empty, code still "use" `i`.
Error still exist in 9.1
