使用QT与DLL与-MT崩溃编译

问题描述：

我的代码是这样的（我的计划是与MT释放模式太）：

int main(int argc, char *argv[]) 

{ 
    int ret = 0; 

    if(0 == ret) 
    { 
     QApplication a(argc, argv); 
     { 
      test01 w; 
      w.show(); 
      ret = a.exec(); 
     } 
    } 

    return ret; 
} 

test01 is very simple like this: 

class test01 : public QMainWindow 

{ 
    Q_OBJECT 

public: 
    test01(QWidget *parent = 0); 
    ~test01(); 

private: 
    Ui::test01Class ui; 
};

一切正常，但是当离开的主要功能，它坠毁：
