            Bug ID: 23254
           Summary: Nested name specifier refers to injected class name,
                    not the constructor
           Product: clang
           Version: 3.6
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

>From the StackOverflow question: http://stackoverflow.com/q/29681449/1287251

The code:

#include <iostream>
struct B
{
};

struct C
{
  C (){ std::cout << "C" << '\n'; }
  C (B *) { std::cout << "C (B *)" << '\n';}
};

B *y = nullptr;
int main()
{
  C::C (y);
}

compiles with clang 3.5 and 3.6 and prints "C". This should not be valid code,
though, as C::C should refer to the constructor (and not the inject class name
C).
