Guidance regarding reporting a bug probably related with VectorAPI

[Joel Knighton]

This appears to be the same issue I reported in an earlier thread:
https://mail.openjdk.org/pipermail/panama-dev/2023-October/020072.html. I
can reproduce on an AVX-512 machine with hsdis, and the crash is at an
indexed load.

Best,
Joel
