클래스의 문자열로 인한 C++ 메모리 누수

Question

Visual C++ 2010에서 개발 중이며 "Visual Leak Detector"라는 라이브러리를 사용하여 메모리 누수를 확인합니다. 그런 다음 설명하고 해결할 수없는 것을 발견했습니다.

이

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

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

헤더 파일은 다음과 같습니다 : 여기 내 코드입니다

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

UPDATE : 그것은 여기라고 :

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; 
    } 
} 

그리고 4 개의 메모리 누수의 스택이 매우이다 유사하므로 여기에 그 중 하나가 있습니다.

Answer 1

IOgreCommand (또는 IOgreCommand에서 파생되는 모든 클래스)에 가상 소멸자가없는 경우 IOgreCommand에서 파생되는 클래스에는 IOgreCommand 포인터를 삭제할 때 소멸자가 호출되지 않습니다.
