Description
Describe the issue:
We noticed a regression with numpy 2.0.1 in yt's test suite yt-project/yt#4953, which bisects to gh-26821
This crash (segmentation fault) pops up in a test that use numpy's RNG (seeded), but it is still non-deterministic: it doesn't always happen, though it is frequent enough that I can reliably hit it locally if I run the test a dozen times.
As a shortcut get a MWE, I saved the random-generated data to a .npy file (uploaded to filetransfer.io, see link in the reprod script)
I suspect the important change in gh-26821 is that Highway is now used by default on macOS+arm64
may be linked to gh-27023
Reproduce the code example:
import numpy as np
# https://filetransfer.io/data-package/VZDHbBLq#link
arr = np.load("array.npy")
np.unique(arr)Error message:
