           Summary: Use of multiple using declaration in a function scope
                    (Another erroneous compilation)
           Product: clang
           Version: 2.8
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org

ISO C++ 7.3.3/8 says - "A using-declaration is a declaration and can therefore
be used repeatedly where (and only where) multiple declarations are allowed."

So

namespace A{
   int i;
}

int main(){
   using A::i;
   using A::i;
}

is ill-formed according to the Standard. But Clang erroneously compiles the
above code snippet.
