--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
A simple change like this (changing everything to struct causing everything to
be public) shows the problem has been there since GCC 8 (when
-mforce-indirect-call support was added).
```
template <class Derived>
struct base {
friend void bar(Derived& d) {
d.bar();
}
};
struct derived : base<derived> {
friend class base<derived>;
void bar() {}
};
int main() {
derived d;
bar(d);
}
```
-mforce-indirect-call -fPIC -fprofile-generate -g0
```
