一种内存泄漏的代码

内存泄漏的地方经常比较隐秘，今天就遇到了一回。问题出在delete (void*)上面，示例代码如下：

class Detect
{
public:
    Detect()
    {
        m_n1 = 0;
        m_n2 = 0;
        m_data.resize(10 , 0);
    }
    virtual ~Detect()
    {
    }

protected:
    int m_n1;
    int m_n2;
    deque<short> m_data;
};

class Monitor
{
public:
    Monitor()
    {
        m_pDetect = new Detect;
    }
    ~Monitor()
    {
        if (m_pDetect != 0)
        {            // 加上这行代码就避免泄漏内存
            //((Detect*)m_pDetect)->~Detect();
            delete m_pDetect;
            m_pDetect = 0;
        }
    }

    bool detect()
    {
        return true;
    }

protected:
    void* m_pDetect;
};
