我有一个项目正在处理,我对 std 映射有一些奇怪的行为。
我有自己的 typedef 映射定义了将字符串映射到自定义类型的指针。在我将第一对添加到地图后,只要我超出地图,应用程序就会崩溃。
经过一番混乱后,我将地图更改为 a 并将其移至应用程序中的第一个调用,但它仍然崩溃。我不知道会发生什么。任何帮助,将不胜感激。
这是目前崩溃的代码。
LoggerPtr syslogger(Logger::getLogger("CISInterface"));
int main(int argc, char *argv[])
{
typedef std::map<string, string> MyMapDef;
MyMapDef tmpString;
tmpString.insert(MyMapDef::value_type("0000", "d"));
tmpString.insert(MyMapDef::value_type("1111", "d")); //Crashes here.
tmpString.insert(MyMapDef::value_type("2222", "d"));
// std::string configFile;
// int c;
// if(argc < 2)
// {
// //Must have c option
// std::cout << "Usage -c configFileName" << std::endl;
// exit(EXIT_FAILURE);
// }
//Rest of main commented out.
...
这是堆栈跟踪 -

我应该关注哪些其他领域可能会导致问题。它可能在我链接的库中吗?我创建了第二个项目,只有这些代码行链接到相同的库(但没有任何代码调用它们。)并且它不会崩溃。
