我正在尝试使用Boost的序列化功能来序列化派生类。我的基类没有不同的数据成员，所以派生类只有这个serialize()函数:

template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
    ar & boost::serialization::base_object<Car>(*this);
}

那么基类有这个serialize()函数:

template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
    ar & color;
    ar & miles;
    ar & model;
    ar & doors;
}

将此添加到基类中没有区别:

BOOST_SERIALIZATION_ASSUME_ABSTRACT(Car)

程序编译得很好。main()生成一些虚拟数据，将其打印到标准输出，然后使用boost序列化将其保存。然后，它尝试从文件中读取数据并打印结果。它可以很好地保存数据，并且我可以打开数据文件并确认数据确实存在。

但是，当重新构建派生类(以及重新构建基类的实例)时，它会在基类的serialize()函数开始时失败。任何想法吗?我想我做了一切正确的例子，从提供的增强网站。提前谢谢你。此外，我在Mac OS X上使用GCC 4和最新的boost库(来自源代码)，并且示例程序在不处理继承时可以很好地使用boost。

更新:在尝试运行Boost文档http://www.boost.org/doc/libs/1_42_0/libs/serialization/doc/tutorial.html#derivedclasses:

中的示例代码时，我也遇到了同样的问题。

class bus_stop_corner: public bus_stop {
friend class boost::serialization::access;
friend ostream& operator<<(ostream &out, const bus_stop_corner &bsc);
template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
    // serialize base class information
    ar & boost::serialization::base_object<bus_stop>(*this); // Fails here
    ar & street1;
    ar & street2;
}
string street1;
string street2;
virtual string description() const {
    return street1 + " and " + street2;
}
public:
bus_stop_corner(){}
bus_stop_corner(const gps_position & lat_, const gps_position & long_, const string & s1_, const string & s2_): bus_stop(lat_, long_), street1(s1_), street2(s2_) {}
};

对于ar & boost::serialization::base_object<bus_stop>(*this);, GDB表示EXC_BAD_ACCESS。
