It seems like pickle tests started to crash at build 936, 4 days ago:
https://buildbot.python.org/all/#/builders/402/builds/936
This build was trigged by the change:
commit fcb3d2f
Author: Mark Shannon <mark@hotpy.org>
Date: Mon Oct 11 11:34:02 2021 +0100
I don't know if the commit is related to the crash or not.

Hopefully this was fixed by #29258
sweeneyde commentedon Oct 30, 2021
Looks like the pickletester bug hasn't happened since the fix, so I'll go ahead and close this.
