Just saw another on openbsd-386 at 4a8dbaa (but passed before & after):

I'm going to tag this Go 1.5 until we at least understand it. If it ends up being an OpenBSD-specific thing, we wouldn't hold up the release for it.

@bradfitz bradfitz added this to the Go1.5 milestone May 7, 2015

Given the lack of activity, I assume this has resolved itself or is openbsd-specific. If the issue should be reopened, please remove the Go1.5 milestone.
