    Description

      Using V8 Javascript engine, using the prefix in-place addition operator in a signal handler in QML causes a crash:
      I.e. the following qml code causes a crash:
      onFooChanged: ++bar

      It seems to work fine in the onClicked handler, and bar++ works fine too.

      A simple example is attached.
