[Boost-users] Serialization problem

Hello, I try to use serialization of boost. I have started with the exemple of bus stop in XML : http://www.boost.org/libs/serialization/example/demo_xml.cpp I have added to this example a map of 1000 bus_schedule. Then I save this map in a file. And I relaod this file in a new map. This works perfectly in XML, but if I try : binary_iarchive I got an boost::archive::archive_exception at memory location 0x00dfdb40.. I don't understand why It woks in XML and not in binary. I have attached to the mail the source file. If someone could help me It would be great ! Thanks. -- Christophe Loustaunau.
