The following code crashes in for_each when trying to output the 1st pair.
What's wrong with it?

Thanks!

namespace bl = boost::lambda;
std::map<std::string, std::string> temp;
temp["a"] = "1";
temp["b"] = "2";
const std::map<std::string, std::string> attrs(temp);
typedef std::pair<std::string, std::string> string_pair;
std::stringstream stream;
std::for_each(attrs.begin(), attrs.end(),
   stream << bl::bind(&string_pair::first, bl::_1)
<< bl::bind(&string_pair::second, bl::_1));
