Android: Toplevel QGLWidget crashes on startup

Apps that consist of a toplevel QGLWidget (such as the cube example) crash on startup with 5.3.0. A QGLWidget child will work (such as the hellogl_es2 example).

This is a minimal example that crashes with 5.3.0, but works in 5.2.1:

#include <QApplication>
#include <QGLWidget>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QGLWidget w;
w.show();

return a.exec();
}

UPDATE:

The crash is caused by QAndroidPlatformBackingStore::QAndroidPlatformBackingStore doing a static_cast<QAndroidPlatformRasterWindow *> on a QAndroidPlatformGLWindow.
