Comment From: bcmills
Part of the test is currently skipped on linux/386 as of CL 376656 (#49182, #50504).
Perhaps that skip should be extended to openbsd/386 as well?
(Marking as release-blocker, but since openbsd/386 is not a first class port this can be resolved by updating the skips in the test.)
Comment From: cherrymui
On OpenBSD we use libc for syscalls. We generally cannot unwind the C stack if the signal arrives in the libc functions. Perhaps for short term skipping on all OpenBSD sounds reasonable. But I still don't understand why we get into sigpanic. I think we should not use sigpanic for externally-generated SIGSEGV. Maybe sigcode is not correct on OpenBSD/386?

Only one of these this year and it's not a first-class port, and (unlike openbsd-amd64-68) this builder appears not to be a TryBot.
If the builder gets too noisy I'll remove it from triage, but I don't think this needs to be a release-blocker.
Comment From: cherrymui
OpenBSD 6.8 is no longer a supported version of OpenBSD. Our https://github.com/golang/go/wiki/MinimumRequirements documents that we only support the current stable version, which is OpenBSD 7.1. Maybe we can remove OpenBSD 6.8 builders and close this.

Rolling forward to 1.20. Please comment if you disagree. Thanks.
