C++ global extern “C” friend can't reach private member on namespaced class

Question

Please consider the code:

#include    

using namespace std;

extern  \"C\"
void    foo( void );

namespace   A
{
    template< int No >
           


        

Answer 1

It's a g++ bug. Exists in 4.4, fixed in 4.6.

UPD: It seems that it's triggered by a combination of template and namespace. extern "C" is not relevant, as it may be commented out and the error remains.
