      using QGLWidget in qt-4.6.0 (I get the source from gitorious) will cause several memory leaks. This can be produced by the following program:

      int main(int argc, char *argv[])
      {
      	QApplication a(argc, argv);
      
      	QGLWidget w;
      	w.show();
      
      	int ret = a.exec();
      
      	int tmp = _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG);
      	tmp |= _CRTDBG_LEAK_CHECK_DF;
      	_CrtSetDbgFlag(tmp);
      
      	return ret;
      }
      

      you can see the leak after running this program with a debug version
