+Description of Problem:
+mcs throws exception after signaling error message
+
+Steps to reproduce the problem:
+1. Try to compile following errornous code:
+
+using System;
+
+class X {
+  public bool operator == (X a, X b) { return true; } 
+
+  public static bool operator != (X a, X b) { return false; } 
+  
+    static void Main ()
+    {
+      X a = new X();
+      Console.WriteLine (a == null);
+    }
+}
+
+
+Actual Results:
+t.cs(4) error CS0558: User defined operators 'X.operator == bool(X,X)' must
+be declared static and public
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
