+Summary: Error in hiding inherited members
+
+Description of Problem:
+Declaration of a private member in a subclass should not hide an inherited
+public member
+
+Steps to reproduce the problem:
+using System;
+
+class Base {
+        public void F () { Console.WriteLine ("Base.F"); }
+}
+
+class Derived : Base {
+        new private void F () { Console.WriteLine("Derived.F"); }
+}
+
+class MoreDerived : Derived {
+        public void G () { F (); }
+}
+
+class Test {
+
+        public static void Main ()
+        {
+                MoreDerived m = new MoreDerived ();
+
+                m.G ();
+        }
+}
+
+Actual Results:
+The program prints "Derived.F": the call to F in MoreDerived.G resolves to
+Derived.F.
+
+Expected Results:
+That call should resolve to Base.F (the program should print "Base.F").
+
+How often does this happen? 
+Always
+
+Additional Information:
+This bug is (probably) related to the fact that accessibility is not 
+currently checked by mcs.
