      Description

      Apparently you can crash the QML engine by assigning negative values to widths of Flickables. In my test case this is probably caused by an integer overflow. To reproduce first revert https://codereview.qt-project.org/#change,72018 in QtCreator, then open the timeline view in the Qml Profiler and repeatedly select smaller and smaller ranges until it starts glitching, then flick around a bit, lather, rinse, repeat until it crashes.

      Backtrace:
