Looks like your correct. I've made a change which I think will address the problem. Robert Ramey Richard Crossley wrote:

Hi,

I'm trying to read in a xml_archive created by a previous version of the serialization library (version="3") with the version from CVS head (version="4").

The reading fails in load_collection here as there is no "item_version" field.

if(3 < ar. get_library_version ()){ ar >> BOOST_SERIALIZATION_NVP(item_version); }

Shouldn't a xml_archive be doing a set_library_version() based on the version of the archive it's reading, or am I missing something?

Regards,

Richard.
