+Summary: [GMCS] Compiler error with the '==' operator when comparing interface reference against class reference
+
+Compile the following code with gmcs:
+
+public interface IContainer
+{
+}
+
+public interface IExtContainer : IContainer
+{
+}
+
+public abstract class ObjectContainerBase : IContainer
+{
+}
+
+public class Program
+{
+    public static void Main(string[] args)
+    {
+        IExtContainer e = null;
+        ObjectContainerBase b = null;
+        System.Console.WriteLine(e == b);
+    }
+}
+
+It fails with:
+
+Operator `==' cannot be applied to operands of type `IExtContainer' and
+'ObjectContainerBase'
+
+Expected result:
+
+No errors.
