ASSERT failed in windows 8 QWindowsMsaaAccessible::childPointer



  • I Built QT for Windows 8 from source and when i create a simple QGraphicsView with a single button the application fails to run with an assertion failure with the following stack trace
    @
    Qt5Cored.dll!qt_message_fatal(QtMsgType __formal, const QMessageLogContext & context, const QString & message) Line 861 C++
    Qt5Cored.dll!QMessageLogger::fatal(const char * msg, ...) Line 356 + 0xf bytes C++

    However on windows 7 everything seems to be working fine.

    This is the code i tried
    @
    #include <QtWidgets/QApplication>
    #include <QGraphicsScene>
    #include <QGraphicsView>
    #include <QGLWidget>
    #include <QPushButton>

    int main(int argc, char argv[])
    {
    QApplication a(argc, argv);
    QGraphicsScene scene;
    QGraphicsView view;
    QPushButton
    button = new QPushButton("Click Me!");
    scene.addWidget(button);
    view.resize(1024,768);
    view.setScene(&scene);
    view.setSceneRect(0,0,1024,768);
    view.show();
    return a.exec();
    }
    @

    Any ideas on what is causing this issue?
