Ah, ok, I don't see the same with gcc 7.3 on x86_64. No problem there
though, and no need for more testing. It's just interesting.

Yeah, I saw that in your other e-mail after replying.

I've filed a bug for it:


and you can consider it reviewed by me. If you post a formal approval
(see [0]), then we can get it fixed. At the moment, there's both a review
and approval process for 8u, while it's maintained by Oracle.

It'll get pulled into the aarch64 tree when we sync with a release the
fix is in (I'd assume around the time of the April security update).
