I think I have figured out the problem.  I had a locally built and cached wheel of PyQt5-sip from before PEP573 went in.  If that wheel is used for later commits I get the segfault, if I rebuilt the wheel from source it works.

I am not sure if this is an expected sharp edge (wheels are be expected to be good between commits prior to a release) or not.

Below is a script that will build everything (sip, pyqt5, pyqt5-sip) from source and install them into a virtual env.

#! /usr/bin/bash
set -e

rm -r ~/.pybuild/py39 || true

./configure --prefix=/home/tcaswell/.pybuild/py39
make -j 9
make install

~/.pybuild/py39/bin/python3 -m venv --copies --clear ~/.virtualenvs/py39



source ~/.virtualenvs/py39/bin/activate
pip install --upgrade pip
