Following the twisted maze that is BOOST_CLASS_EXPORT() leads me to think that
it is (very) roughly equivalent to this:
void dummy(boost::archive::xml_iarchive ar, A a, B b) {

If I add simple explicit instantiations in place or in addition to the
BOOST_CLASS_EXPORT() calls, all symbols are correctly exposed in all cases :
namespace boost {
namespace serialization {

Thanks a lot for considering this report!

Also since it is not explicitly instatinated, the template does not need to be
in the object file really.
I believe this is instantiated

I believe this is instantiated with Archive = boost_xml_iarchive by the
BOOST_EXPORT macro.
I mean BOOST_CLASS_EXPORT(), of course, sorry.

serialize with an empty body is a pure function so it will be can be optimized
away without any effects. I don't see the issue here really.

Can you give a better example of why do you think this is wrong besides a nm
testcase? It might be due to
