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.

Please attach the compiled .exe.

Created an attachment (id=170901)
compiled .exe which throws the exception

The runtime side of this bug is fixed in svn.
I asked the binary because the gmcs compiled exe worked fine.
The difference is that csc compiles the enum to a generic inst class
with the generic parameters of the nesting generic class.
Since this is a user-visible difference, gmcs should likely do the same.
