[New-bugs-announce] [issue46070] broken subinterpreters

[graysky]

New submission from graysky <graysky at archlinux.us>:

Seems as though cpython is broken when working with subinterpreters. The problematic change could be (d0d29655ff) affecting import.c.[1] Reverting this commit and rebuilding python fixes the issues on my system with some scripts that import sqlite, for example, the Kodi plugin YouTube[2] and the IMDB Trailers plugin. Others have reported similar breakage with other python code[3].

Example output when the bug manifests:

ERROR <general>: Traceback (most recent call last):
