ports/unix: standard build crashes with segfaults often on Apple M1 (macOS Ventura 13.4)

I am unable to get micropython to work on my Mac Mini M1.

I get segfaults very often. 43% of the tests in make test fail.

I have done:

git pull
cd ports/unix
make clean submodules
make

Here's an easy test case:

[ned@Neds-mini [ (git)-[master]-] ports/unix] % build-standard/micropython
MicroPython v1.20.0-189-gfd277704c on 2023-06-10; darwin [GCC 4.2.1] version
Use Ctrl-D to exit, Ctrl-E for paste mode
>>> a = array()
zsh: segmentation fault  build-standard/micropython

I'm running an Apple Mac Mini (M1, 2020) under Ventura 13.4

I am able to reproduce the crash. I did a git bisect and traced the introduction of the bug to 2757acf.

Example stack trace of the crash:
