From: Alexander Gutenev (gutenev_at_[hidden])

The example below works in 1.40 and fails in 1.41
#include <string>
#include <sstream>
#include <vector>
#include <boost/smart_ptr.hpp>
#include <boost/serialization/serialization.hpp>
#include <boost/serialization/shared_ptr.hpp>
#include <boost/serialization/vector.hpp>
#include <boost/archive/xml_oarchive.hpp>
#include <boost/archive/xml_iarchive.hpp>
struct X
: boost::enable_shared_from_this<X>
{
X(){}
virtual ~X() {}
explicit X(int i) : i(i) {}
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
ar & boost::serialization::make_nvp("i", i);
(void) version;
}
int i;
};
typedef boost::shared_ptr<X> PX;
typedef std::vector<PX> VPX;
int main()
{
std::ostringstream oss;
VPX vpx;
vpx.push_back(PX(new X(2)));
vpx.push_back(PX(new X(5)));
vpx.push_back(PX(new X(7)));
boost::archive::xml_oarchive oa(oss);
oa << boost::serialization::make_nvp("v", vpx);
vpx.clear();
std::string s = oss.str();
std::istringstream iss(s);
boost::archive::xml_iarchive ia(iss);
ia >> boost::serialization::make_nvp("v", vpx);
PX px = vpx[1].get()->shared_from_this();
return 0;
}
