Description
This problem has been separated from QTBUG-93298.
Attached simple reproducer that demonstrates the issue with calling QThread::terminate() on destruction of some object in Qt Quick items hierarchy.
Steps to reproduce:
1. Build and run (in Debug mode) attached project
2. Close the window and observe assertion
There is recursive call of object's destructor in stack trace:
