<pre>Test case:
namespace P{ namespace X { static int i = 1; } }
namespace Q { namespace X = P::X; }
using namespace P;
using namespace Q;
int main() { X::i; }
Command line:
clang++ prog.cc -std=c++14 -pedantic-errors
This results in name-lookup ambiguity errors when looking up X in main. This is
not a name-lookup ambiguity since the two names founds denotes the same entity.</pre>
