类中的C++设置字符串属性值正在引发“访问冲突读取位置”

我很难让这个简单的代码工作:

#pragma once
#include <iostream>
#include <string>
using std::string;

class UserController;
#include "UserController.h"
class CreateUserView
{
public:
 CreateUserView(void);
 ~CreateUserView(void);
 UserController* controller;
 void showView();

 string name;
 string lastname;
 string address;
 string email;
 string dateOfBirth;
};

我只需要在getline()实现中设置这些属性。

CreateUserView::CreateUserView(void)
{

}
void CreateUserView::showView()
{

 cout << endl << "  New User" << endl;
 cout << "--------------------------" << endl;
 cout << "  Name\t\t: ";
 getline(cin, name);

 cout <<  "  Lastname\t: ";
 getline(cin, lastname);

 cout << "  Email\t\t: ";
 getline(cin, email);


 cout << "  ===============================" << endl;
 cout << "   1. SAVE   2.CHANGE   3.CANCEL" << endl;
 cout << "  ===============================" << endl;
 cout << "  choice: ";
 int choice;
 cin >> choice;
 cin.ignore();

 controller->createUser_choice(choice);
}

我一直在这一行得到“访问冲突读取位置”错误:

getline(cin, name);

为类的std::string属性赋值的最佳方法是什么? 即使name=“whatever”也会抛出错误!!

谢谢

编辑: 用户控制器正在实例化CreateUserView:

CreateUserView *_createUserView;

CreateUserView的实例化方式如下:

void UserController::createUser()
{
    //Init the Create User View
    if(_createUserView == NULL)
    {
        _createUserView = new CreateUserView();
        _createUserView->controller = this;
    }
    _createUserView->showView();
}
