1774	serialization: file written with 1.34.1 can't be read in with 1.35	filippeters@…	Matthias Troyer	"std::vectors of basic types, saved with 1.34.1, can't be read by 1.35:

simple sample, write file with 1.34.1:
	std::vector<unsigned int> vectorToSave;
	vectorToSave.push_back(0);
	vectorToSave.push_back(1);
	vectorToSave.push_back(2);

    
    std::string filename(""C:\\test1341.xml"");
	{
	    std::ofstream ofs(filename.c_str());
	    assert(ofs.good());
	    boost::archive::xml_oarchive oa(ofs);
	    oa << BOOST_SERIALIZATION_NVP(vectorToSave);
	}

And with 1.35:
	std::vector<unsigned int> vectorToLoad;
    std::string oldfilename(""C:\\test1341.xml"");
	try{
		std::ifstream ifs(oldfilename.c_str());
		assert(ifs.good());
		boost::archive::xml_iarchive ia(ifs);

		// restore the schedule from the archive
		ia >> BOOST_SERIALIZATION_NVP(vectorToLoad);	
	}
	catch(...){
	    std::cout << ""\nproblem"";
	}

This will end up in the catch.
