    Description

      How to reproduce

      Run attached main.qml with qmlviewer & 'QML_DISABLE_OPTIMIZER' environment variable set:

      Starting /home/kkoehne/dev/qt/qt-4.8/bin/qmlviewer -I /home/kkoehne/dev/qt/qt-4.8/imports /home/kkoehne/dev/tmp/disableOptimizerBug/main.qml
Qml debugging is enabled. Only use this in a safe environment!
file:///home/kkoehne/dev/tmp/disableOptimizerBug/main.qml:11: Unable to assign QObject* to MyPageStack_QMLTYPE_0*
/home/kkoehne/dev/qt/qt-4.8/bin/qmlviewer exited with code 0

      Without the QML_DISABLE_OPTIMIZER environment variable set, the app runs without the warning.
