 I assume I have missunderstood the bug - a testcase would be really
 helpful

+Here i a test case adapted from delegate4.cs:
+
+using System;
+using System.Threading;
+using System.Runtime.InteropServices;
+using System.Runtime.Remoting.Messaging;
+
+class Test {
+	public delegate int SimpleDelegate (int a, int b);
+
+	[DllImport ("libtest.so", EntryPoint="mono_invoke_delegate")]
+	static extern int mono_invoke_delegate (SimpleDelegate d);
+
+	public static int CallBack (int a, int b) {
+		Console.WriteLine ("CallBack: " + a +  " + " + b);
+		return a + b;
+	}
+	
+	public static int BackCall (int a, int b) {
+		Console.WriteLine ("BackCall: " + a +  " + " + b);
+		return a + b;
+	}
+
+	static void Main () {
+		SimpleDelegate d = new SimpleDelegate (CallBack);
+		SimpleDelegate d1 = new SimpleDelegate (BackCall);
+		mono_invoke_delegate (d);
+		mono_invoke_delegate (d1);
+		d.DynamicInvoke (new Object[] {2,3});
+		d1.DynamicInvoke (new Object[] {2,3});
+	}
+}
+
+the output from mono is:
+
+start invoke 0x8249c08
+CallBack: 2 + 3
+end invoke
+start invoke 0x8249c08
+CallBack: 2 + 3
+end invoke
+CallBack: 2 + 3
+BackCall: 2 + 3
+
