[Bug c++/33468] C++: Invalid interpretation of friendness with nested classes

[bangerth at dealii dot org]

------- Comment #1 from bangerth at dealii dot org  2007-09-18 18:59 -------
Confirmed.

A simpler to understand testcase is this one (all crud removed):
-----------------
class A {
    class B { };
    friend class X;
};
class X {
    A::B mx;
    class Y : A::B {
        A::B my;
    };
};
----------------
It shouldn't compile because X::Y is not a friend and therefore can't
access A::B in the declaration of 'my', as noted in 11.4/2.

This is a regression introduced in gcc 4.0.x. We get the correct error
in everything leading up to 4.0.3, but not any more in 4.0.4. This
may help figure out which patch is at fault...
