c++ - 无法访问地址 0x1 处的内存

Question

我有三个基类 {Player,Weapon,Game} 和一个从 Player 继承的 Class Warrior。我添加的代码可能不是最少的，但我添加了任何相关的内容。因为不知道去哪里找。

这是我对简单调试的测试，我将 Players 添加到在 game.h 中定义的 vectorPlayers

int main() {
    Weapon w1("hello",STRENGTH,3);
    Game game(3);
    game.addWarrior("s22","we",STRENGTH,3,55);
    //4
    game.addWarrior("s22","we",STRENGTH,3,55);
    return 0;
}

当我到达第 4 行时，vectorPlayers[0] 包含正确的输入。但是当我进入game.cpp并在addWarrior中调用函数addPlayer时，例如players_name突然切换到 错误：Cannot access memory at address 0x1

//inside game.cpp


GameStatus Game::addPlayer(const string playerName, const string weaponName,
                                   Target target,int hit_strength)
        {
            Weapon newWeapon(weaponName,target,hit_strength);
            Warrior newWarrior(playerName,newWeapon,false);
            if(ifNameAlreadyExists(playerName)) {
                addRegPlayer(static_cast<Player*>(&newWarrior));
            }
            return SUCCESS;
        }

        GameStatus Game::addRegPlayer(Player* player)
        {
            playersVector.push_back(player);
        }


        //base classes

            class Game {

            private:
                int maxPlayer;
                vector<Player*> playersVector;
        }

        class Player {
                string player_name;
                int level;
                int strength;
                Weapon player_weapon;
            protected:
                int place;
                int life;
            public:
            Player(const string &name, const Weapon &weapon);
            virtual ~Player();
                }


        //inherited class

        class Warrior : public Player {
        private:
            bool rider;
        public:
            Warrior ();
            Warrior (string const& name, Weapon const& weapon, bool rider);
            ~ Warrior () override = default;
            Warrior &operator=(const Warrior &warrior) ;
            Warrior ( const Warrior &warrior) = default;
            void makeStep() override;
        };


        //Constructor of Warrior
        Warrior::Warrior(string const& name, Weapon const& weapon, bool rider) :
                Player(name,weapon),rider(rider){
            if (weapon.getTarget() == LEVEL){
                throw IllegalWeapon();
            }
        }
        //constructor of player
        Player::Player(const string& name, const Weapon& weapon) :
                level(1),life(1),strength(1),player_weapon(weapon),player_name(name),place(0){
        }
