異常拋出0x00007FF746DA221B SDL_game.exe：0xC0000005：訪問衝突讀取位置0xFFFFFFFFFFFFFFFF

Question

我想調試我的應用程序，我不斷收到此錯誤，我不知道如何解決它。在調試過程中，我發現錯誤的地方在於函數parseObjects。它還調用創建遊戲對象工廠是如下功能...

GameObject* GameObjectFactory::create(std::string typeID) { std::map<std::string, BaseCreator*>::iterator it = m_creators.find(typeID);

if (it == m_creators.end()) 
{ 
    std::cout << "could not find type: " << typeID << "\n"; 
    return 0; 
} 

BaseCreator* pCreator = (*it).second; 
return pCreator->createGameObject();} 

這一點，調用一個造物主對象後，成功地加載參數加載功能，但是，當它試圖將對象推回到向量中，它會收到上述錯誤。

... 
    e->Attribute("x", &x); 
    e->Attribute("y", &y); 
    e->Attribute("width", &width); 
    e->Attribute("height", &height); 
    e->Attribute("numFrames", &numFrames); 
    e->Attribute("callbackID", &callbackID); 
    e->Attribute("animSpeed", &animSpeed); 

    type = e->Attribute("type"); 
    textureID = e->Attribute("textureID"); 

    GameObject* pGameObject = TheGameObjectFactory::Instance()->create(type); 
    pGameObject->load(new LoaderParams(x, y, width, height, textureID, numFrames, callbackID, animSpeed)); 
    pObjects->push_back(pGameObject); // fails on this line ??? 
}` 

調試器進入這一行向量... bool _Inside(const value_type *_Ptr) const { // test if _Ptr points inside vector return (_Ptr < this->_Mylast() && this->_Myfirst() <= _Ptr); }

任何幫助和建議將不勝感激...

我認爲這可能發生，因爲你的載體pObjects將不會被初始化或者某種損壞的狀態。
