            Bug ID: 16818
           Summary: friend from different namespace doesn't work when
                    return type is provided indirectly
           Product: clang
           Version: 3.3
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

The code below doesn't compile. It compiles if you replace returning type
"type" with void. The code compiles on gcc 4.7.3. the code compiles if you
remove the "d" namesapce.

#include <iostream>

namespace n {

    namespace d {
        struct A;
    }

    class ReplacedType {
        public:
            typedef void type;
    };

    //forward declaration
    ReplacedType::type
    f(d::A);

    namespace d {
        struct A {
            typedef    ::n::ReplacedType::type type;
            friend 
             type
//           void
                ::n::f(A);
            private:
            int a;
        };
    }


        ReplacedType::type
        f(d::A a) {
        std::cout << a.a <<std::endl;
    }
}

int main() {

    return 0;
}
