13456,Object tracking fails with pointer to variant's content,Ricardo Calheiros de Miranda Cosme <ricardo.cosme@…>,Robert Ramey,"Object tracking fails with a pointer to an object contained into a variant that is an element of a container which loads the value_type into a local object. For example a map with a variant as a mapped_type.

Demo:

{{{
struct Foo
{
    int i;

    template<typename Archive>
    void serialize(Archive& ar, const unsigned int version)
    { ar & i; }
};

int main()
{
    using map_t = std::unordered_map<std::string, boost::variant<Foo, float>>;
    std::string testfile{""/tmp/serialized""};
    {
        map_t map{{""key"", Foo{5}}};
        auto ptr = &boost::strict_get<Foo>(map.begin()->second);
        
        std::ofstream os(testfile);
        boost::archive::text_oarchive oa(os);
        oa << map;
        oa << ptr;
    }
    {
        std::ifstream is(testfile, (std::ios_base::openmode)0);
        boost::archive::text_iarchive ia(is, 0);

        map_t map;
        Foo* ptr;
        
        ia >> map;
        ia >> ptr;
        
        assert(ptr->i == 5);
    }
}
