I had to trim a bit the source to be make the preprocessed source fit into 1000
ko. With it, the expected nm output (-O2 -fno-inline-small-functions) is:

00000000 W void
boost::serialization::serialize<boost::archive::xml_iarchive>(boost::archive::xml_iarchive&,
A&, unsigned int)
 00000000 W void
boost::serialization::serialize<boost::archive::xml_iarchive>(boost::archive::xml_iarchive&,
B&, unsigned int)

And the one with missing symbols (-O2) is:
 00000000 W void
boost::serialization::serialize<boost::archive::xml_iarchive>(boost::archive::xml_iarchive&,
B&, unsigned int)
