[Mono-list] OnDeserialization problem

[Dave Null]

Hi,

I'm trying to use the IDeserializationCallback interface with Mono 2.2  on
OS X 1.5.6 :

% mono --version
Mono JIT compiler version 2.2 (tarball Fri Jan  9 10:45:07 MST 2009)
Copyright (C) 2002-2008 Novell, Inc and Contributors. www.mono-project.com
	TLS:           normal
	GC:            Included Boehm (with typed GC)
	SIGSEGV:       normal
	Notification:  Thread + polling
	Architecture:  x86
	Disabled:      none

For my test, i've simply created a class which implements the interface and
the OnDeserialization() method :

[Serializable] class Truc : IDeserializationCallback {
	private int limite;
	[NonSerialized] private int[] tab;
       (...)
       public virtual void OnDeserialization(Object sender) {
	  for (int i = 0; i < limite; i++) {
	    tab[i] = i + 42;
	  }
	}
       public static void Main() {
	  Truc truc = new Truc(20);
	  Console.WriteLine(truc);
	  truc.Dump();
	  Truc machin = Truc.Load();
	  Console.WriteLine(machin);
	}
}

This code compile fine with gmcs but execution throws an
System.NullReferenceException :

% mono serialisation2.exe
42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61

Any clue ?
