signalFree may segfault under pydev

Running the snippet below under pydev (PyCharm's debugger) causes a segmentation fault in PySide6's signalFree():

from PySide6.QtCore import *
app = QCoreApplication([])
QThread(app)
class Foo(QObject):
    ready = Signal()

Not sure if the issue lies with pydev or PySide6, though I wasn't able to reproduce this crash with your competitor.

pydev is launched via PyCharm with the following command:

/opt/homebrew/bin/python3 -X pycache_prefix=/Users/u/Library/Caches/JetBrains/PyCharmCE2024.2/cpython-cache /Applications/PyCharm\ CE.app/Contents/plugins/python-ce/helpers/pydev/pydevd.py --multiprocess --qt-support=pyside6 --client 127.0.0.1 --port 52573 --file signalfree1.py 

Attached is a macOS crash report. I could reproduce this on Linux as well.

Python 3.13.0, PySide6 6.8.0.2.
