NND,这都能错.解决办法

NND,这都能错....

C/C++ code

#include <ext/hash_map>#include <string>int main(){    __gnu_cxx::hash_map< std::string, int > testMap;    std::string str = " 狗日的,这都能错 ";    std::string & rStr = str;    __gnu_cxx::hash_map< std::string, int >::iterator it = testMap.find(str);    /*或者:    __gnu_cxx::hash_map< std::string, int >::iterator it = testMap.find(rStr);    */    return 0;}
