Subject: [Mono-dev] gmcs compiler exception (was Re: Call for testing:

When attempting to compile the attached code, gmcs fails:

$ gmcs test.cs

Unhandled Exception: Mono.CSharp.InternalErrorException: test.cs
(4,33): Test.ExtensionHandler ---> System.ArgumentNullException:  
Argument cannot be null.

   at Mono.CSharp.Driver.Main (System.String[] args) [0x00000]

This is the code:

public class Test {
     public static void Main(string[] argS) { }
     private delegate object ExtensionHandler(params object[] args); }

Removing params from the delegate declaration avoids the compiler error
