Perhaps:

   template<int N>
+  struct A {
+    A() { static_assert(N == 0, ""); }
+    A(int, double) { static_assert(N == 1, ""); }
+    A(int, int) { static_assert(N == 2, ""); }
+    A(std::initializer_list<int>) { static_assert(N == 3, ""); }
+
+    int operator[](A);
+  };

+  void initialization() {
+    { A<0> a{}; }
+    { A<0> a = {}; }
+    { A<3> a{1, 1.0}; }
+    { A<3> a = {1, 1.0}; }
+    { A<3> a{1, 2, 3, 4, 5, 6, 7, 8}; }
+    { A<3> a = {1, 2, 3, 4, 5, 6, 7, 8}; }
+    { A<3> a{1, 2, 3, 4, 5, 6, 7, 8}; }
+    { A<3> a{1, 2}; }
+  }

I did some other tests that I posted to a GCC PR. If you want you can add 
them here too: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47453#c3
