[Boost-users] [Serialization] Can't Serialize vectors of user-defined classes

hi all. I recently tried to execute this very simple example: #include <iostream> #include #include #include #include <fstream> class A { public: A(){} private: //Serialization tasks friend class boost::serialization::access; template<class Archive> void serialize(Archive & , const unsigned int ) { } }; int main() { std::vector<A> eig; std::cout <> eig; } std::cout < >, std::allocator > > > >]: Assertion `! detail::singleton_wrapper<T>::m_is_destroyed' failed. Curiously, the comportment of the gcc 4.1.2 of codepad is not the same: http://codepad.org/sEK2fLua Curiously, this works fine on my compiler when i olny serialize A but not with the codepad compiler: http://codepad.org/j3wlsWDv Do you have any clue about this problem ? Thanks
