You have this code:

void Player::PickupCards(const int NumberOfCards)   // pickup a certain amount of cards from our global deck
{
	//...
	for (list <Card>::iterator i = Deck.Contents.begin(); i != Deck.Contents.end(); ++i) // go backwards....
    {
        Hand.push_front(i);       // take the last value from the deck, and put it into that players hand
        Deck.Contents.pop_front();                       // remove the last value of the deck, shortening it, so value was removed

	//...
    }
}

When you do a pop_front you invalidate the iterator i. Therefore, you have undefined behaviour.
