Question

When I close my app in a certain state, this code runs:

void GameEndState::exit(){
    delete m_pGameObjectManager;
    delete m_pSceneManager;
}

After running m_pGameObjectManager’s destructor, which is:

GameObjectManager::~GameObjectManager(){
    std::for_each(gameObjects.begin(),gameObjects.end(),GameObjectDeallocator());
}
//gameObjects is a std::map<sf::String,VisibleGameObject*>

///////////////

struct GameObjectDeallocator{
        void operator()(const std::pair<sf::String,VisibleGameObject*>&p) const{
            delete p.second;
        }
    };

it will produce the title’s error. I haven’t found any results of this error from googling. I am using SFML 2.0.

VisibleGameObject’s destructor:

VisibleGameObject::~VisibleGameObject(){
    m_pSceneManager->removeSprite(name);
}

void SceneManager::removeSprite(sf::String spritename){
    std::cout << "removed " << std::string(spritename) << std::endl;
    sprites.erase(sprites.find(spritename));
}

//sprites is a std::map<sf::String,sf::Sprite>

Thanks in advance

The error is in this line, evidently sprites.find is not finding the name you’ve given it and is returning sprites.end().

sprites.erase(sprites.find(spritename));
