[Boost-users] Serialization valgrind reports errors in load() ...

Hello, I have following class which I want to serialize: template < class ValueType > class Values { private: vector< ValueType > _values; public: Values(unsigned p_nr, const ValueType& p_value) : _values(p_nr, p_value) {} Values() {} private: friend class boost::serialization::access; template < class Archive > void load(Archive& p_ar, unsigned /*p_version*/) { p_ar & _values; } template < class Archive > void save(Archive& p_ar, unsigned /*p_version*/) const { p_ar & _values; } BOOST_SERIALIZATION_SPLIT_MEMBER(); }; My main() looks very simple: ... // save const Valuesstd::string a(3, "fritz"); { std::ofstream ofs("fritz.txt"); boost::archive::text_oarchive ar(ofs); ar << a; } // restore Valuesstd::string b; { std::ifstream ifs("fritz.txt"); boost::archive::text_iarchive ar(ifs); ar >> b; } valgrind reports me following errors (the load() seems to be the problem): ==13202== Conditional jump or move depends on uninitialised value(s) ==13202== at 0x4E59F72: boost::archive::detail::basic_iarchive::reset_object_address(void const*, void const*) (in /usr/lib64/libboost_serialization.so.1.33.1) ==13202== by 0x408A2C: boost::serialization::stl::archive_input_seqstd::string >

I don't see any mistakes in my client code. Seems to be a problem of the boost::serialization library. (I'm using boost 1.33.1) Should I create a bug entry for that, or is it already known? Regards, Sascha
