--- Comment #2 from Toni Neubert <lutztonineubert at gmail dot com> ---
Copy paste error. The above example should be:
```
struct A {
constexpr virtual int get() = 0;
constexpr virtual int set(A *o) = 0;
};
struct B : A {
constexpr int get() override {
return 10;
}
constexpr int set(A *o) override {
a = o;
return 20;
}
A *a{};
};
constexpr auto addressof = [](A &n) {
return &n;
};
struct Foo {
B b[1];
A* curr_{addressof(b[0])};
constexpr int add() {
return curr_->set(addressof(b[0]));
}
};
constexpr int get() {
Foo f;
return f.add();
}
constexpr auto a = get();
int main() {
return a;
}
```
