           Summary: gmcs generating invalid IL with extension methods.
           Product: Mono: Compilers
           Version: 1.2
          Platform: 64bit
        OS/Version: openSUSE 10.3
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#
        AssignedTo: rharinath at novell.com
        ReportedBy: benji.weber at gmail.com

          Found By: ---


The following code compiles with 

gmcs ./Test.cs -langversion:linq


but when run it fails with 

Unhandled Exception: System.InvalidProgramException: Invalid IL code in
Test:Main (string[]): IL_0001: call      0x06000003

I'm not certain whether the code is valid or not, but there is no compiler
error.

using System;

public class Test
{
        public static void Main(String[] args)
        {
                if(1.OneEleven())
                        Console.WriteLine("Hmm");
        }
}

public static class Lol
{
        public static bool OneEleven(this object o)
        {
                return true;
        }
}
