1.44 As I wrote, I am able to debug deep into boost mpi and archive. Please let me know if I should send any more stacks or other data,
Please try with 1.45. Pointer serialization in Boost.MPI has been broken in 1.44 due to changes in Boost.Serialization.

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
