dead loop in QWindowsFontDatabaseFT::populate()

In windows platform plug-in there is a function QWindowsFontDatabaseFT::populate(), it will call EnumFontFamiliesEx() to enumerate font families, that function will enter a dead loop and never return.
The following program can reproduce this problem:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QPushButton b("Hello World!");
    b.show();
    
    return a.exec();
}
