And apparently there are significant differences between the source distribution and v2.3.2 git tag (and main, so to say).

Hi, I am not sure how to reproduce this error, can you tell me what source distribution you are referring to?
Also can you walk me through your steps to reproduce the issue, and maybe a pip freeze of your packages? It looks like you are using the system-installed pytest, what version is that?
