Re: [Boost-users] XML-Serialization_Problem with loading...

I'm suspicious of

oa << BOOST_SERIALIZATION_NVP(*fixt);

This assigns an XML tag name of <*fixt> which I suspect isn't kosher.  You 
might try:

oa << boost::serialization::nvp("fixt_tag", *fixt);

See if that helps.

BTW,   I find things like

oa << *x;

very odd.  Its not clear what the intention is to me.

I would have written
