      Description

      Hello there. I saw a very strange checked QGroupBox that I couldn't uncheck by mouse. I tried to reproduce the problem and managed to shorten it in the following code snippet.

      #include <QApplication>
      #include <QDebug>
      #include <QGroupBox>
      
      int main(int argc, char *argv[])
      {
          QApplication app(argc, argv);
          QGroupBox box;
          box.setCheckable(true);
          box.setTitle("Title");
          int i = 100;
          bool *a = reinterpret_cast<bool *>(&i);
          qDebug() << int(*a);
          box.setChecked(*a);
          box.show();
          return app.exec();
      }
