c++0x: member template fails with a strange error (4.5.1)

[Edward PieÅkowski <edek dot pienkowski at gmail dot com>]

Hello,

I have a problem with getting member template resolution right, using gcc 4.5.1.

Is this a bug, or is it some standard quirk? (or maybe I just managed
to miscompile gcc, though bootstrap was done)


This is fine:
----------------------------------------------------------------------------------------------------------------------

#include <memory>

class AA {
public:
    template <class T> void doSomething () {};
};

class CC {};

class BB {
    std::shared_ptr<AA> a_ptr;
public:
    void something () {
       this->a_ptr->doSomething<CC> (); // OK
       a_ptr->doSomething<CC> ();       // OK
       AA().doSomething<CC> ();         // OK
    }
};
---------------------------------------------------------------------------------------------------------------------

This fails in one case: (bug2.h)
----------------------------------------------------------------------------------------------------------

#include <memory>

class AA {
public:
    template <class T> void doSomething () {};
};

class CC {};

template <class T>    // THIS LINE ADDED
class BB {
    std::shared_ptr<AA> a_ptr;
public:
    void something () {
       this->a_ptr->doSomething<CC> (); // FAILS
       a_ptr->doSomething<CC> ();       // OK
       AA().doSomething<CC> ();         // OK
    }
};
------------------------------------------------------------------------------------------------------------------

It fails with the following:
