+Summary: Exception: Invalid IL code
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+I have an application compiled with Microsoft .NET 2.0, but it gives an 
+"System.InvalidProgramException: Invalid IL code" when run on Mono 
+(1.1.15 as well as 1.2)
+
+Steps to reproduce the problem:
+1. 
+Compile following program with Microsoft 2.0:
+
+using System;
+using System.Collections.Generic;
+using System.Text;
+
+namespace ConsoleApplication1
+{
+//  public enum TestEnum { one, two, three }     // (1)
+  class Parent<T, U>
+  {
+    protected enum TestEnum { one, two, three }  // (2)
+    protected TestEnum te;
+  }
+  class Child : Parent<int, int>
+  {
+    public void DoIt()
+    {
+      te = TestEnum.one;                 
+      Console.WriteLine(te.ToString());
+    }
+  }
+  class Program
+  {
+    static void Main(string[] args)
+    {
+      Child C = new Child();
+      C.DoIt();
+    }
+  }
+}
+
+2. 
+3. 
+
+Actual Results:
+
+Unhandled Exception: System.InvalidProgramException: Invalid IL code in 
+ConsoleApplication1.Child:DoIt (): IL_0002: stfld     0x0a000011
+
+
+  at <0x00000> <unknown method>
+  at ConsoleApplication1.Program.Main (System.String[] args) [0x00000]
+
+
+Expected Results:
+
+
+How often does this happen? 
+
+Always.
+
+Additional Information:
+
+The program works if you put line (2) in comment and uncomment line (1). 
+It might be a problem with Generics, because it works when Parent has no 
+generic type parameters.
