[Mono-list] Bug related to operator += and instance fields

[Rodolfo Campero]

Hello everybody,

I've found a bug, but I'm not sure about how to report it (I mean I can't 
find a suitable subject and other info):

The following source code compiles but its execution results in incorrect 
behavior:

<code>
using System;
namespace Test {
  public class A {
    public static void Main () {
      A a = new A ();
      a.Test ();
    }

    public void Test ()
    {
      A a = new A ();
      // the following is the problematic line
      _intValue += a.Value + a.Value / 2;
      Console.WriteLine (_intValue);
    }

    private int _intValue;
    public readonly int Value = 100;
  }
}
</code>

The actual result is 50 but I think it should be 150.

I need someone to give me instructions about the affected product 
(Mono/Compilers or Mono/Runtime or ...) and a suitable subject if possible, 
or to tell me that this is not a bug and I'm plain wrong :-)

If someone can file the bug report for me it's ok too.

TIA,

Rodolfo
