Hello, I am trying to save and load a vector > > to an axml archive. I am able to save the xml archive properly, but I cannot read the saved archive. I have examined the XML file that is generated and it does not seem to have any errors. I get the following assertion error when I try to load the file. Any help would be appreciated. Thank you, Thomas /include/boost/serialization/collections_load_imp.hpp:69: void boost::serialization::stl::archive_input_map::operator()(Archive&, Container&) [with Archive = boost::archive::xml_iarchive, Container = std::mapstd::string, std::allocator >

]: Assertion `result.second' failed.
