While QTBUG-60604 was fixed in 5.9.0, it broke again in 5.9.1.

1. Open sensor_explorer example in Creator.
   It's in Examples\Qt-5.9\sensors\sensor_explorer\sensor_explorer.qml
2. Configure it to use MSVC2013 64 bit in Release mode.
3. Try to build the project.
   Building fails:

   .qtquickcompiler\sensor_explorer_qml.cpp(1783) : error C2143: Syntaxfehler: Es fehlt ';' vor 'Typ'
   .qtquickcompiler\sensor_explorer_qml.cpp(1783) : error C3409: Ein leerer Attributblock ist nicht zul„ssig
   .qtquickcompiler\sensor_explorer_qml.cpp(1783) : error C2059: Syntaxfehler: '='
   .qtquickcompiler\sensor_explorer_qml.cpp(1783) : error C2143: Syntaxfehler: Es fehlt ';' vor '{'
   .qtquickcompiler\sensor_explorer_qml.cpp(1783) : error C2447: '{': Funktionsheader fehlt - Parameterliste im alten Stil?
   

It should be possible to build this example. Building succeeds when using any of the following:

• MSVC2015
• Qt 5.8
• disabling Qt Quick Compiler
