这是 Valgrind 的输出:

==6519== by 0x403A55: main (main.cpp:32)
地图中的每个条目都会重复同样的错误。
main.cpp第32行是:
pilInpOpts input;
pilInpOpts 的第 12 行是构造函数的一部分:
#include "pilInpOpts.h"
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
pilInpOpts::pilInpOpts()
{
// create the map of options, put in alphabetical order to ease sorting
piloptmap.insert(std::pair<std::string, bool>("bforce",false));
piloptmap.insert(std::pair<std::string, bool>("coef",false));
piloptmap.insert(std::pair<std::string, bool>("dualjet",false));
piloptmap.insert(std::pair<std::string, bool>("flow",false));
piloptmap.insert(std::pair<std::string, bool>("gforce",false));

// need to define the default filepaths, this is needed because they are optional
platpath = "";
vehpath = "";
apppath = "";
dockpath = "";
};
我在 SO 中发现一些帖子说 Valgrind 可能会产生误报。例如:std::string 内存泄漏 https://stackoverflow.com/questions/13001784/c-stdstring-memory-leak
这是误报吗,因为 std::string 具有执行此操作所需的所有构造函数等?或者我应该更改为在地图中使用 C 字符数组?
