           Summary: Friend declaration is ignored
           Product: clang
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: bjorn at topel.se
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com


The following code snippet (which works for GCC 4.5 and VC 7):

functor.cc:

template <class T>
struct Functor {
};

class Class {
    struct Inner {
        int a_;
    };

    friend struct Functor<Inner>;
};

template <>
struct Functor<Class::Inner> {
    int operator() (Class::Inner const & key) const
    {
        return key.a_;
    }
};


yields:

functor.cc:14:23: error: 'Inner' is a private member of 'Class'
struct Functor<Class::Inner> {
                      ^
functor.cc:6:12: note: declared private here
    struct Inner {
           ^
1 error generated.
