TST: OSX job sometimes fails with Illegal instruction

[pllim]

Seems transient. I see different jobs failing in the last 2 scheduled runs, but both are OSX; e.g., py310-test-pytest70 (macos-latest), py311-test-pytest73 (macos-latest)

Fatal Python error: Illegal instruction

Interesting, I wonder what goes wrong with those OSX virtual machines, as we do see (totally different, yet always OSX) issues with them with sphinx-automodapi, too.

And now pytest-doctesplus is also experiencing OSX issues, and of course, it's yet a different one: https://github.com/scientific-python/pytest-doctestplus/actions/runs/7382066201/job/20176149354#step:5:112

However, it's really hard to believe these there issues are not connected in some ways as the common theme that the errors started to show up out of the blue and only affect OSX CI (I haven't been able to reproduce the problems locally on a mac)

The doctestplus failure is due to pytest-dev, not OSX. I see a similar failure on astropy running Linux but also using pytest-dev: https://github.com/astropy/astropy/actions/runs/7375363390/job/20170602594

ah, interesting that it doesn't effect either linux or windows.

Ah, I didn't see that you also have pytest-dev in Linux and Windows. Yes, that is indeed perplexing and also does not explain why astropy sees a similar error (but from a different plugin) in Linux.

maybe an overkill, but it's a pytest plugin with a really quick test suite, so I think it makes most sense to test thoroughly.
