I referred to JDK-8233199 because it seems both panama-vector and valhalla-repo have the same issue/crash. @PaulSandoz also mentioned that panama-vector was not in sync with master and this is perhaps the issue is in vector-unstable. He said that he tested the PR separately and didn't observe this issue in the PR. - PR: https://git.openjdk.java.net/jdk/pull/367

The code in this pull request is from vector-unstable branch. The bug report https://bugs.openjdk.java.net/browse/JDK-8233199 refers to repo-valhalla and not panama-vector:vector-unstable. @PaulSandoz is doing final testing of the pull request today before integration tomorrow hopefully. - PR: https://git.openjdk.java.net/jdk/pull/367

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.
