+Summary: Cast from enum variable to System.Enum gives null
+
+Build and run the following:
+
+using System;
+
+class Test {
+
+ public enum MyEnum { A, B, C };
+
+ public static void Main()
+ {
+ MyEnum me = MyEnum.A;
+ System.Enum se = (System.Enum) me;
+ IConvertible ic = (IConvertible) se;
+ if (ic == null) {
+ Console.WriteLine("null");
+ }
+ }
+}
+
+Actual Results:
+
+It prints 'null'
+
+Expected Results:
+
+Under csc/ms runtime it gives no output.
+
+Additional Information:
+
+Actually, it's the cast from MyEnum to System.Enum gives null on mono.
+However, I've left the code snippet exactly as it was when I tested it on a
+windows box at work today, so I'm sure of the behaviour on windows.
