Boost version : 1.44

j ai une erreur lors de la serialization d une liste d object et je ne comprend pas pkoi.
Si la taille de la list est inferieur ou egale a 25 , tout marche bien mais sinon ca plante.

Voila mon code, c est juste pour faire des tests donc pardonner moi d avance sur la proprete:

	}
	return 0;
 
}
Dans le main :
- MapPoints mapPoint (30);
- mapPoint.buildMap();
Ceci va construire une liste de 30 objects gps_position.
Et lors de la serialization ca va planter.
Par contre si vous remplacer le 30 par 20 ca va fonctionner .

Une idee ?
