Not a bug. You are using TPAR inside the class C1<T>::S,
however, only C1<T> is a friend of C2. This is the relevent section
of C++ standard (section 11.4 paragraph 2):
... the declarations of members of classes nested within
the friend class cannot access the names of private and
protected members from the class granting friendship. ...
and the example in the same section:
class A {
class B {};
friend class X;
};
class X : A::B { // ill-formed: A::B cannot be accessed
// in the base-clause for X
A::B mx; // OK: A::B used to declare member of X
class Y : A::B { // OK: A::B used to declare member of X
A::B my; // ill-formed: A::B cannot be accessed
// to declare members of nested class of X
};
};
