Hello,

Some time ago I asked a question about taking an address of protected
member function:

"C2248: cannot access protected member"
http://groups.google.com/group/microsoft.public.vc.language/browse_frm/thread/a6b6afdca3ea91a2/

Recently I discovered that proposed solution fails to compile with
VC++2008 if the classes are nested and member function is referenced via
fully qualified name:

class Outer
{
class X;
class Y;
};

class Outer::X
{
protected:
void foo() {}
int a;
};

class Outer::Y : public Outer::X
{
public:
void bar()
{
void (Outer::Y::*pf)() = &Outer::Y::foo; // C2248
int Outer::Y::*pa = &Outer::Y::a; // C2248
}
};

If I omit the `Outer' part, then everything compiles smoothly:

void (Outer::Y::*pf)() = &Y::foo;
int Outer::Y::*pa = &Y::a;

Comeau C++ online test compiles the code either way, so I believe it's a
bug in VC++ 2008.

Before I open a bug report, do I miss something here?

Thanks
Alex

The fact that 2010 is almost out the door? Just a thought. Might want
to verify the behaviour and file the bug against that too (or not).

Good idea. Currently I don't have VS 2010 at hand to check it out.
Could anybody of the readers of this group check the code with
VC++ 2010?

I'll do it at home tonight if I remember to.

I get the same errors in VC++ 2010 RC.
g++ 3.4.4 and 4.3.4 both accept it without error.
