Console C++ Application1.exe a déclenché un point d'arrêt

lorsque je tente de régler

cub.SetArray(cube);

J'obtiens une erreur

Console Application1.exe has triggered a breakpoint 

Ce que je fais mal? Lorsque j'essaie de débogage cub -> cubesarray je obtenir la taille -842150451. Je ne comprends pas pourquoi.Voici mon code
