 Additional Information:
 note that compiling the same code with csc gives correct results on both
 mono and .net runtimes. Compiling with mcs gives incorrect on both -
 leading me to belive that its a code generation issue with mcs.

+Simpler:
+class X {
+	public virtual int Foo () {            
+		return 1;
+	}
+}
+
+class Y : X {
+
+	delegate int D();
+	
+	
+	D GetIt () {
+		return new D (base.Foo);
+	}
+	
+	public override int Foo () {
+		return 0;
+	}
+	
+	static void Main ()
+	{
+		System.Console.WriteLine (new Y ().GetIt () ());
+	}
+}
+
+Should print 1.
+
+The problem is we generate this code:
+    .method private hidebysig
+           instance default class 'Y/D' GetIt ()  cil managed
+    {
+        // Method begins at RVA 0x20ff
+        // Code size 14 (0xe)
+        .maxstack 8
+        IL_0000:  ldarg.0
+        IL_0001:  dup
+        IL_0002:  ldvirtftn instance int32 class X::Foo()
+        IL_0008:  newobj instance void class 'Y/D'::.ctor(object,
+native int)
+        IL_000d:  ret
+
+
+ldvirtftn is wrong.
