    Description

      The application crashes when dynamic_casting eventFilter()'s first parameter 'QObject obj' to a QWidget. qobject_casting works.

      The crash happens while eventFilter() is called with an obj originating from Qt5WebEngineCored, see attached screenshot.

      A minimal application which reproduces the crash is attached.

       

      PS: There is the class MessagePumpForUIQt which inherits QObject, but has no Q_OBJECT-Macro.
