Not sure exactly how long this has been happening, but the macOS arm64 CI job on Cirrus is crashing fairly regularly right now. This happened both before and after the downgrade of the Highway git submodule to 1.0.7

The CI logs show things like:

________________________ _core/tests/test_multiarray.py ________________________
[gw1] darwin -- Python 3.10.11 /private/var/folders/c2/b2kmn__12wq57m82ltz0hl1w0000gn/T/cibw-run-3g7m_5go/cp310-macosx_arm64/venv-test/bin/python
worker 'gw1' crashed while running '_core/tests/test_multiarray.py::test_sort_float[e-N151]'

It's not just that one test, there are multiple tests and input values that crash.

It could be multiple things, but gh-25247 is probably the first thing to check (Cc @Mousius).
