[Bug c++/36911] New: Virtual function problem

["david dot golub at yale dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

When a virtual function is called from a base class constructor, it always
calls the base class's version of the function, even if a derived class
overrides it.  Example code:

#include <iostream>
using namespace std;

class Base {
public:
        Base();
        virtual void overridable();
};

class Derived : public Base {
public:
        virtual void overridable();
};

void Base::overridable() {
        cout << "Base::overridable called" << endl;
}

Base::Base() {
        overridable();
}

void Derived::overridable() {
        cout << "Derived::overridable called" << endl;
}

int main() {
        Derived obj;
        return 0;
}

Output: Base::overridable called
Should be: Derived::overridable called
