I doubt its a problem with the library but try this:

{    std::ifstream ifs("filename");
    {
        boost::archive::text_iarchive ia(ifs); // <--- causes a segfault.
    }
}

platforms which don't destroy everything in the reverse sequence
of creation would have problems which would be addressed
by this change.
