The warning keeps libboost_serialization.a and libboost_wserialization.a from building. A simple work around is to remove the no throw specification 'throw ()' from the base class' virtual destructor. I believe the long term fix is to update the definitions of the derived classes to correctly include the no throw specification to match the base class.

Your best bet is to file a trac ticket, attach a patch, and prod the list and/or author. I added "[serialization]" to the subject to increase the chances this'll be seen by Robert. Your mentioned this occurs many times for various source(s?). Is it isolated to the Boost.Serialization sources, or do you get this warning elsewhere as well? - Jeff
