将double转换为字符串.Boost Libraries似乎不起作用,sstream导致"SEG FAULT"

#include<iostream>
#include <sstream>
#include<boost/lexical_cast.hpp>

int main() {
    double num = 123.45;

    // 使用Boost Libraries将double转换为字符串
    std::string str1 = boost::lexical_cast<std::string>(num);
    std::cout << "Boost Libraries: "<< str1<< std::endl;

    // 使用C++标准库中的sstream将double转换为字符串
    std::ostringstream str2;
    str2<< num;
    std::cout << "C++ standard library: "<< str2.str()<< std::endl;

    return 0;
}
