 Its a race condition in your code, which means that whether the async
 thread gets the new or old version of "data" is random.

+Well, now I've modified my code as following:
+
+private void Listen()
+{
+  byte[] data = null;
+  EndPoint endPoint = null;
+  int recv = 0;
+                                                                     
+                              
+  while (!isDisposed) {
+    if (socket.Poll(PollTimeOut, SelectMode.SelectRead)) {
+      data = new byte[socket.Available];
+      endPoint = (EndPoint) localEndPoint;
+                                                                     
+                              
+      recv = socket.ReceiveFrom(
+        data,
+        0,
+        data.Length,
+        SocketFlags.None,
+        ref endPoint);
+                                                                     
+                              
+      if (recv > 0) {
+        Datagram datagram = NetConverter.ToDatagram(data, 0);
+        ReceiveEventArgs e = new ReceiveEventArgs(datagram);
+                                                                     
+                              
+        if (Receive != null) {
+          Receive(this, e);
+        }
+      }
+    }
+  }
+}
+
+In the code above, Poll() is not executed until the datagram
+is completely received by ReceiveFrom()... but I'm still
+not able to receive Multicast and Broadcast datagrams.
