This is a spin out of a problem mentioned in PR13092.
The following testcase shouldn't compile because only
fr<int> is friend of class D.  But we are accessing
protected members from fr<char>.  GCC 3.4, 3.5 fail
to diagnose it.  Earlier GCC don't handle this properly
(checking access while parsing the template fr<T> which
is too early.)  So it's not a regression.


// Two-phase name lookup for address of member:
// Protected member access

class B
{
  protected:
  int i;			// { dg-error "protected" }
};

template <class T> void fr ();

class D2 : public B
{
  friend void fr<int> ();
};

template<int B::*> struct X
{};

template <class T> void fr ()
{
  X<&B::i> x1;			// { dg-error "context" }
  X<&D2::i> x2;			// { dg-error "context" }
}

template void fr<char>();	// { dg-error "instantiated" }
