+Summary: delegates not going through RealProxy/Transparent Proxies correctly
+
+Given the following code:
+
+---- t11.cs ----
+using System;
+using System.Runtime.Remoting;
+using System.Runtime.Remoting.Messaging;
+using System.Runtime.Remoting.Proxies;
+
+public abstract class TestClass : MarshalByRefObject {
+  public abstract void Foo ();
+}
+
+public class TestProxy : RealProxy {
+  public TestProxy (Type baseType) : base (baseType)
+  {
+  }
+
+  public override IMessage Invoke (IMessage msg) {
+    Console.WriteLine ("Invoke: ");
+    Console.WriteLine (msg.GetType());
+
+    IMethodCallMessage mcall = msg as IMethodCallMessage;
+
+    IMethodReturnMessage ret = new ReturnMessage (null, null, 0,
+						  mcall.LogicalCallContext,
+						  mcall);
+    Console.WriteLine ("Finish");
+    return ret;
+  }
+}
+
+public class Driver {
+  public delegate void FooDelegate();
+
+  public static void Main () {
+    TestProxy tp = new TestProxy (typeof(TestClass));
+    TestClass tc = (TestClass) tp.GetTransparentProxy();
+
+    FooDelegate fd = new FooDelegate (tc.Foo);
+  }
+}
+---- end ----
+
+mono 0.26 (whatever CVS is around aug 20) crashes with a failed assertion:
+
+** ERROR **: file object.c: line 670 (mono_object_get_virtual_method):
+assertion failed: (res)
+
+This is caused because the method in question is declared as abstract; if
+the method were given a concrete implementation in TestClass, then the test
+does not crash, but produces incorrect results: the proxy is entirely
+bypassed with the delegate.
