1f77d4709946511b919810354f19875824399096 (qt/qtwebengine/5.12)
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.
