Interesting. collection_size_type is std::size_t:
BOOST_STRONG_TYPEDEF(std::size_t, collection_size_type)
and in some implementations std::size_t is 'unsigned long'. If you
then use this implementation on two platforms where
'unsigned long' have different sizes, you will get incompatible
archives. In my experience with portable binary archives (we are
going way back to boost 1.32), it was necessary to choose a size (e.g.
handle collection_size_type explicitly and cast to uint64_t, for
example).
Cool archive, in any event. boost::serialization is incredibly useful stuff.
