C++ Cannot use push_back on list containing custom structs - c++

Question

We are making a list that hold info on boardgames (name, year, score). We scan the info out of a .csv file, make a struct based on that info and then add the struct to a list. We keep doing this untill the document is done reading. Problem is that the push_back method of the list doesn't work. Here's the header of the list class:
NOTE BoardGame is the custom struct. BoardGame(wstring name, int year, float score).
#pragma once
#include "GameEngine.h"
#include "BoardGame.h"
#include <list>
class BoardGameList
{
public:
BoardGameList() {}
virtual ~BoardGameList() {}
// Methods
void Load(const tstring& fileName);
// Members
private:
std::list<BoardGame> m_Games;
};
The cpp file. Maybe I made the list the wrong way?
#include "BoardGameList.h"
#include <fstream>
void BoardGameList::Load(const tstring& fileName)
{
tifstream file(fileName);
tstring line;
if(!file)
{
GAME_ENGINE->MessageBox(_T("Error: The file could not be found!"));
}
else
{
tstring name;
tstring year;
tstring score;
while(!(file.eof()))
{
getline(file,line);
year = line.substr(0,4);
score = line.substr(5,5);
name = line.substr(11,line.find(_T("\n")));
float numberScore = std::stof(score);
int numberYear = std::stoi(year);
m_Games.push_back(BoardGame(name,numberYear,numberScore));
}
}
}
Running the program triggers an error (unhandled exception) that leads me to the following code in the "list" class itself I think.
_Unchecked_iterator _Unchecked_end()
{ // return unchecked iterator for end of mutable sequence
return (_Unchecked_iterator(this->_Myhead, this));
}
Any ideas why I can't add stuff to my list? I tried adding something in the constructor to check if it maybe needed an element before I could add more but even then, using a breakpoint showed me that the memory could not be read.
Many thanks in advance.
EDIT: Header of BoardGame
#pragma once
#include "GameEngine.h"
struct BoardGame
{
BoardGame(tstring name, int year, float score);
//Methods
tstring operator<<(BoardGame rhs);
//Members
tstring m_Name;
int m_Year;
float m_Score;
};

Answer 1

What exception is being thrown? This is vital to debugging your problem.
Without that information my best guess is this line:
name = line.substr(11,line.find(_T("\n")));
Will throw an exception on any line without a trailing newline, or any line less than 11 characters long.
