c++ - 崩溃 : Segmentation fault: Boost serialization loading - calling constructor with null

Question

我正在使用 C++ boost 库 1.6.3 将游戏的主类序列化并保存到文本文件，其中附加了不同的类作为指针和引用、数组和基本类型变量，问题是当我加载文件，它崩溃并给出以下输出:

Assertion failed: register_type(bpis_ptr->get_basic_serializer()) == cid, file libs\serialization\src\basic_iarchive.cpp, line 454

问题是这个类与其他序列化的类相似，并且没有错误。

按照 boost::serialization 指令序列化这就是我正在做的事情:1)在基类中:添加序列化访问的友元类，以及要序列化的函数，例如:

class BJShoe 
{
    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive & ar, const unsigned int file_version)
    {
        ar & BOOST_SERIALIZATION_NVP(totalCards);
        ar & BOOST_SERIALIZATION_NVP(cards);
        ar & BOOST_SERIALIZATION_NVP(numCards);
    }
    protected:
    int totalCards[10],
        cards[10],
        numCards;
}

所以，对于主类，我有这样的东西:

class Game {
    int numDecks;
    bool hitSoft17;
    bool doubleAnyTotal;
    bool double9;
    bool doubleSoft;
    bool doubleAfterHit;
    bool doubleAfterSplit;
    bool resplit;
    bool resplitAces;
    bool lateSurrender;
    int dealerSpeed;
    BJStrategy maxValueStrategy;
    Progress progress;
    // Release all objects on exit
    BJRules *rules;
    Player *strategy;
    Hand *dealer;
    Probabilities *dealerProbabilities;
    Shoe *shoe;
    BJShoe *distribution;
    PlayerHand *tempHand;
    //counters and game-loop vars
    int lastWager;
    int balance;
    Card tempCard;
    PlayerHand playerHands[4];
    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive &ar, const unsigned int version)
    {
        ar.template register_type<BJShoe*>();
        ar.template register_type<PlayerHand*>();
        //etc.
        ar.template register_type<BJShoe>();
        ar.template register_type<PlayerHand>();
        cout << "numDecks\n";
        ar & BOOST_SERIALIZATION_NVP(numDecks);
        cout << "hitSoft17\n";
        ar & BOOST_SERIALIZATION_NVP(hitSoft17);
        cout << "doubleAnyTotal\n";
        ar & BOOST_SERIALIZATION_NVP(doubleAnyTotal);
        cout << "double9\n";
        ar & BOOST_SERIALIZATION_NVP(double9);
        cout << "doubleSoft\n";
        ar & BOOST_SERIALIZATION_NVP(doubleSoft); 
        cout << "doubleAfterHit\n";
        ar & BOOST_SERIALIZATION_NVP(doubleAfterHit); 
        cout << "doubleAfterSplit\n";
        ar & BOOST_SERIALIZATION_NVP(doubleAfterSplit);
        cout << "resplit\n";
        ar & BOOST_SERIALIZATION_NVP(resplit); 
        cout << "resplitAces\n";
        ar & BOOST_SERIALIZATION_NVP(resplitAces);
        cout << "lateSurrender\n";
        ar & BOOST_SERIALIZATION_NVP(lateSurrender); 
        cout << "dealerSpeed\n";
        ar & BOOST_SERIALIZATION_NVP(dealerSpeed);
        cout << "maxValueStrategy\n";
        ar & BOOST_SERIALIZATION_NVP(maxValueStrategy); 
        cout << "progress\n";
        ar & BOOST_SERIALIZATION_NVP(progress);
        cout << "rules\n";
        ar & BOOST_SERIALIZATION_NVP(rules); 
        cout << "strategy\n";
        ar & BOOST_SERIALIZATION_NVP(strategy);
        cout << "dealer\n";
        ar & BOOST_SERIALIZATION_NVP(dealer); 
        cout << "dealerProbabilities\n";
        ar & BOOST_SERIALIZATION_NVP(dealerProbabilities);
        cout << "shoe\n";
        ar & BOOST_SERIALIZATION_NVP(shoe); 
        cout << "distribution\n";
        ar & BOOST_SERIALIZATION_NVP(distribution);
        cout << "tempHand\n";
        ar & BOOST_SERIALIZATION_NVP(tempHand);     
        cout << "lastWager\n";
        ar & BOOST_SERIALIZATION_NVP(lastWager);
        cout << "balance\n";
        ar & BOOST_SERIALIZATION_NVP(balance);
        cout << "tempCard\n";
        ar & BOOST_SERIALIZATION_NVP(tempCard); 

        /*for (int i = 0; i < 4; i++) {
            ar & BOOST_SERIALIZATION_NVP(playerHands[i]);
            cout << "playerHands["<<i<<"]\n";
        }*/
        ar & BOOST_SERIALIZATION_NVP(playerHands);
        cout << "playerHands\n";
    }
}   

2)在子类中，同(1)一样，添加base_object函数，以继承BJShoe的Shoe为例:

boost::serialization::base_object<BJShoe>(*this);

3)导出cpp中的类，示例:

BOOST_CLASS_EXPORT(Shoe)
BOOST_CLASS_EXPORT(BJShoe)

4) 保存函数

void Game::save(const char* filename)
{
    ofstream ofs(filename);
    if (!ofs.good()) return;
    text_oarchive oa(ofs);
    //register all the classes, example:
    oa.register_type<Shoe>();
    oa.register_type<BJShoe>();
    oa.register_type<Game>();
    oa << boost::serialization::make_nvp("game",instance);
    ofs.close();
}

5) 加载函数:

void Game::load(const char* filename)
{
    ifstream ifs(filename);
    if (!ifs.good()) return;
    text_iarchive ia(ifs);
   //register all the classes, example:
    ia.register_type<Shoe>();
    ia.register_type<BJShoe>();
    ia.register_type<Game>();       
    ia >> boost::serialization::make_nvp("game",instance);
    ifs.close();
}

6) 调用保存("play.data");加载(“播放数据”)；导致程序崩溃，这是日志:

我不明白这是否与构造函数或序列化函数有关，因为看起来它正在尝试使用 null 进行初始化，对吧？

Answer 1

我不得不重新编写游戏代码并且添加了所有的复制构造函数；现在它运行正常，正在加载和保存数据。问题在于信息的顺序和构造函数的使用。但是，有时它会因 PlayerHand 指针而崩溃，我必须检查一下。现在的另一个问题是它只适用于 Windows，在 GNU/Linux 中保存数据时，这是新的段错误崩溃日志:
