reassign 877541 golang-1.9
retitle 877541 golang-1.9: Invalid instruction error in i386
thanks

This seems to be an issue with go 1.9, this error is not reproducible
with other versions of go:

$ /usr/lib/go-1.7/bin/go test -c -v
github.com/prometheus/prometheus/storage/local
$ /usr/lib/go-1.8/bin/go test -c -v
github.com/prometheus/prometheus/storage/local
$ /usr/lib/go-1.9/bin/go test -c -v
github.com/prometheus/prometheus/storage/local
# github.com/prometheus/prometheus/storage/local
build/src/github.com/prometheus/prometheus/storage/local/storage_test.go:2028:26:
invalid instruction: 01483
(/tmp/buildd/prometheus-1.8.1+ds/build/src/github.com/prometheus/prometheus/storage/local/storage_test.go:2029)
FMOVD	""..autotmp_78+176(DX)(SP*1), F0


I can't find any reference listing this instruction as valid i386, but
maybe I am not looking correctly.

It is the same issue as #877319. Also, I don't see anything weird in the
code (it faults at the for):

        got := it.RangeValues(metric.Interval{OldestInclusive: 0,
NewestInclusive: 3})
        // Note that we cannot just reflect.DeepEqual(want, got) because
it has
        // the semantics of NaN != NaN.
        for i, gotSamplePair := range got {
                wantSamplePair := want[i]
                if !wantSamplePair.Equal(&gotSamplePair) {
                        t.Fatalf("want %v, got %v", wantSamplePair,
gotSamplePair)
                }
        }
