I'm not sure where to ask this since this isn't actually a Go bug. Go 1.12,
1.1, etc build fine on FreeBSD with ZFS in base. However, with the ZFS
rebased to ZFS on Linux I'm seeing issues that I can only reproduce
building Go. I either see:
from one run:
go install encoding/gob: copying /tmp/go-build309923892/b103/_pkg_.a to
/testpool/freebsd-ports/lang/go/work/go/pkg/freebsd_amd64/encoding/gob.a:
read /tmp/go-build309923892/b103/_pkg_.a: bad address
another:
cmd/pack
cmd/vendor/github.com/google/pprof/internal/elfexec
go install go/types: copying /tmp/go-build100514402/b143/_pkg_.a to
/testpool/freebsd-ports/lang/go/work/go/pkg/freebsd_amd64/go/types.a: read
/tmp/go-build100514402/b143/_pkg_.a: bad address
cmd/go/internal/cache
And dtrace doesn't show any system call returning EFAULT when this happens.
So maybe something in libc? Unclear.
Or from another run:

*** Error code 2
Could someone tell me what it's doing when the first type of failure occurs
and what the STALE error means? I've seen the latter in past issues, but
there was no indication of what that was a symptom of.
Thanks.
