Crash on macOs Sonoma

Hi!

We have been using Pytest-qt for a long time now and we did not have any issues until now. However, after upgrading to macOs Sonoma, I get random crashes during test execution, and the last call is always inside pytestqt. My colleagues executing the same tests on macOs Ventura do not get these crashes. I tried adding an autouse fixture to close all open top level windows, but it did not help. I see it closes several windows, but I still get the crash.

I get tracebacks like this:

    File "python3.10/site-packages/pytestqt/qtbot.py", line 459 in wait
    (unit test function)

Any ideas? I can not reproduce the crash with a single testcase, it only crashes when running the whole suite, and not always at the same place.

Reproduce the intermittent crash by running the full test suite on macOS Sonoma, then inspect the cited entry points: pytestqt/plugin.py (_process_events), qt_compat.py (exec), wait_signal.py (wait), and qtbot.py (wait). Done means identifying the Sonoma-specific cause and preventing the segmentation fault with coverage for the failure.
