           Summary: clang++ permits use of private struct.
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: markus at unixforces.net

clang++ accepts the following code, while g++ does not:


class List {
    private:
        struct Elem {
            Elem* n;
        };
};
int main()
{
    List::Elem a;
}


I'm not entirely sure which one is correct, but I think this should not be
accepted by clang++.
