Hi, robert

Thank you for your answer. My application is mono thread and duplicated 
code for seralization is granted to be the same. Our code actually 
forbide this design. What about replacing line 74&75 of

extended_type_info.cpp :
74        assert(lookup(eti) == m_self->m_map.end());
75 	        m_self->m_map.insert(eti);

by

if ( lookup(eti) == m_self->m_map.end() )
{
    m_self->m_map.insert(eti);
}

? With this new behavior the same type_info can be registred several time.

With this modification my design work fine. I can send you a sample of 
code if you want to investigate the problem

Best regards,

    Vincent Agnus
