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) {
boost::serialization::serialize(ar, a, 0);
boost::serialization::serialize(ar, b, 0);
}
Indeed, replacing my BOOST_CLASS_EXPORT() calls with this, I get the same
effect ("disappearing" symbols with -O2).
At this point, my question is: is triggering template instantiations in this
way supposed to be equivalent to explicit instantiations (as in comment #8)
with respect to symbols exposed to the outside? If the answer is no, thank you
very much for your help and sorry for the trouble.
