I am trying to get the boost::container::map to work on OpenVMS (Alpha). I am getting an %CXX-E-BADBASECLS, (1) invalid base class error but have not been able to track it down. If I use std::map instead of boost::container::map in the code then it will work btw. Thanks for any help, SLDR (Stephen L.
