私は Visual C++ 2010 で開発を行っており、"Visual Leak Detector" というライブラリを使用してメモリ リークをチェックしています。それから、説明も解決もできないものを見つけました。これが私のコードです：

ManageRenderListenerCommand::ManageRenderListenerCommand(string action):mAction(action){
}

void ManageRenderListenerCommand::execute(){
    //Do something with action
}

ヘッダー ファイルは次のとおりです。

class ManageRenderListenerCommand : public IOgreCommand{
private:
    string      mAction;
public:
    ManageRenderListenerCommand(string action);
    void execute();
};

更新:ここで呼び出されます:

void OgreMediator::onOgreChanged(AbstractOgreNegotiator* negotiator, NegotiatorEvent& negotiatorEvent){
    IOgreCommand* command = NULL;
    if(negotiatorEvent.matchEvent("addToViewport")){
        command = new AddToViewportCommand(mCameraManager, mSceneCreator, mEngine);
    }else if (negotiatorEvent.matchEvent("manageRenderListener")){
        command = new ManageRenderListenerCommand(negotiatorEvent.getMessage());
    }else if (negotiatorEvent.matchEvent("manageMouseCamera")){
        command = new ManageMouseCameraCommand(mCameraManager, mMouseManager->getLastEvent());
    }

    //Execute the created command
    if (command){
        command->execute();
        delete command;
    }
}

また、4 つのメモリ リークのスタックは非常に似ているため、そのうちの 1 つを次に示します。

IOgreCommand (または IOgreCommand の派生元のクラス) に仮想デストラクタがない場合、IOgreCommand から派生したクラスは、IOgreCommand ポインタを削除するときに呼び出されるデストラクタを持ちません。
