Hi @PaulSandoz ,

I think it would be better to integrate it [1] in this MR.

I have tested this MR on our AVX512 machines and it still crashes.
Also, for the sake of maintenance, it seems NOT a good idea to push a problematic commit into the jdk main-line repo.

As for the review process, I don't think it's a problem since the fix [1] is clear and small enough.

What do you think?

Thanks.
