Hello Matthias, Robert Ramey,
I am revisiting the topic of mpi broadcast-receiving a polymorphic object
through a base class null pointer:

void recv_histodata(boost::mpi::communicator& world)
{
  historical_data_base* hd = nullptr;
  boost::mpi::broadcast(world, hd, master_process);
}
historical_data_base has 3 derived classes.

I get the unregistered class exception from the serialization library, and
so I am trying to register the derived type as shown in the serialization
doc at /libs/serialization/doc/index.html  : reference

ar.template register_type<derived_one>();

but where do I put that?

Regards,

MM
