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
