[Boost-users] array deserialization problem

25 Jun 2008

      Hi all,

I have a problem deserializing an array. With the code (1) I get a
Segmenetation Fault with stacktrace (2).

Any help appriciated.

Kind regards,
MU.

    boost::archive::xml_oarchive oa(ofs);

    ofs.close();

    // DESERIALIZE:

    boost::archive::xml_iarchive ia(ifs);
    ia >> BOOST_SERIALIZATION_NVP(t2);

    t2->display();

    return 0;
