Graphics / Heap corruption while freeing memory

« on: June 23, 2016, 04:40:16 pm »

Hello guys,

Everytime I try to delete the font variable from memory I get the error "Heap corruption detected. CRT detected that application wrote to memory after end of heap buffer". I realized that when I comment the loadFromFile() method on MainGame.cpp, I don't get the error anymore. I searched on google how to solve the problem and I found some posts that say it happen when you allocate less memory than you really need. As the problem is occurring only with the loadFromFile() method, I came to this forum ask for help.
P.S.: I am using Visual Studio Community 2015. 6GB RAM Memory.

MainGame.h

#pragma once

#include "GameState.h"
#include "MainMenu.h"
#include "PaddlePlayer.h"
#include "Ball.h"
#include "Score.h"

class MainGame : public TinyState
{
public:
        void Initialize(sf::RenderWindow* window);
        void Update(sf::RenderWindow* window);
        void Render(sf::RenderWindow* window);
        void Destroy(sf::RenderWindow* window);

private:
        sf::Font* font;
        PaddlePlayer* player1;
        PaddlePlayer* player2;
        Ball* ball;
        Score* score1;

};

MainGame.cpp

#include "MainMenu.h"
#include "MainGame.h"

void MainGame::Initialize(sf::RenderWindow* window)
{
        this->font = new sf::Font();
        this->font->loadFromFile("Graphics/font.otf");

        //this->score1 = new Score(*font, 64U);

        this->player1 = new PaddlePlayer(0);
        this->player2 = new PaddlePlayer(1);
        this->player2->setPosition(window->getSize().x - this->player2->getGlobalBounds().width,0);

        this->ball = new Ball(player1, player2);
        this->ball->setPosition(window->getSize().x / 2, window->getSize().y / 2);
}

void MainGame::Update(sf::RenderWindow* window)
{
        this->ball->Update();
        this->player1->Update();
        this->player2->Update();
        //this->score1->Update();

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::Escape))
        {
                coreState.SetState(new MainMenu());
        }
}

void MainGame::Render(sf::RenderWindow* window)
{
        //window->draw(*this->score1);
        window->draw(*this->ball);
        window->draw(*this->player1);
        window->draw(*this->player2);
}

void MainGame::Destroy(sf::RenderWindow* window)
{
        delete this->player1;
        delete this->player2;
        delete this->ball;
        //delete this->score1;
        delete this->font; //Problem occurring here
