Question

我使用-MT编译QT动态（修改配置文件）

我的代码是这样的（我的程序也是MT的发布模式）：

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，但是当离开主要功能时，它崩溃了：

将QT与使用-MT崩溃编译的DLL一起使用
