    Description

      There is a stack overflow scenario due to infinite recursion that happens when displaying any QWidget instance. This stack overflow crash is caused by the following code change https://codereview.qt-project.org/#/c/243685/ which fixes QTBUG-71183.

      Sample code is quite basic and is attached.
