FWIW, a few months ago, I looked at a core dump of this and documented
the results here:

https://github.com/scikit-learn/scikit-learn/issues/16443#issuecomment-671063747

Unless I'm misremembering something, the scikit-learn Cython code looks
OK, so the problem probably stems from the code generated from that. It
hat been suggested that some kind of unaligned access is produced.

I stopped debugging there, as it's been a while since I've done
low-level stuff like that.

Best,
Christian
