Description
With a fresh configuration of Qt 5.10.0 from 2017-12-01, and the default "Qt Widgets Application" from Qt Creator, the application compiles but crashes immediately with this output:
Starting /home/rudolf/tmp/build-test_qt_widgets-CustomLinux-Debug/test_qt_widgets...
The program has unexpectedly finished.
The process was ended forcefully.
/home/rudolf/tmp/build-test_qt_widgets-CustomLinux-Debug/test_qt_widgets crashed.
and this stack trace:
