           Summary: gmcs generates invalid IL for creation of anonymous
                    method
           Product: Mono: Compilers
           Version: SVN
          Platform: x86-64
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: vargaz at gmail.com
         QAContact: mono-bugs at lists.ximian.com

As reported by somebody on mono-devel a while ago:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
public class Test
{
   static public void TestFunc ()
   {
       return;

       string testStr;

       System.AppDomain.CurrentDomain.AssemblyLoad += delegate
(object Sender, System.AssemblyLoadEventArgs e)
       {
           testStr = "sss";
       };
   }

   public static void Main (string[] args)
   {
       TestFunc ();
   }
}
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Running the compiled code will fail with:


Unhandled Exception: System.InvalidProgramException: Invalid IL code in
Test:TestFunc (): IL_0024: ldc.i4.4


  at Test.Main (System.String[] args) [0x00000]

This is because TestFunc () doesn't have a 'ret' at the end.
