Details
Description: Python 3.9 breaks Hexchat, it results in core
dumps.
Additional info: * HexChat - hexchat-2.14.3-4-x86_64.pkg.tar.zst * Python - python-3.9.0-1-x86_64.pkg.tar.zst Steps to reproduce: Simply install HexChat and new Python to see this. Workaround: Downgrading back to Python 3.8.6 (including related python libs) and Hexchat 2.14.3-3 seems to at least not crash HexChat. But if hexchat run from terminal you can still see that its produces core dumps. |

The current hexchat Python plugin relies on PyEval_ReleaseLock, which has been deprecated since 3.2. Unfortunately there isn't a clean upstream fix for this as they just rewrote the whole plugin in CFFI (706f9bca82d463f6f1bd17d5dc609807e4a1e8a9).
I'd recommend either disabling the Python plugin for now or use the new Python plugin from master.
Btw, with the current plugin, hexchat will also crash if there is invalid Python syntax in your plugins.
