[openbsd] test_fs_event.py causes Segmentation fault in python

失敗は tests/test_fs_event.py の49行目で報告されています。まず、OpenBSD上で PYTHONASYNCIODEBUG=1 を指定して、提供されている pytest コマンドを実行してください。test_fs_event_change 中に発生する uvloop.loop のセグメンテーションフォールトを調査し、完了時に対象のテストがクラッシュせず完了することを確認してください。

• uvloop version: 0.20.0
• Python version: 3.11.9
• Platform: OpenBSD
• Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Yes
• Does uvloop behave differently from vanilla asyncio? How?:
