Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

1.11

Does this issue reproduce with the latest release?

yes

What operating system and processor architecture are you using (go env)?

GOARCH="amd64"
GOBIN=""
GOCACHE="/home/sherlock/.cache/go-build"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/sherlock/go"
GOPROXY=""
GORACE=""
GOROOT="/usr/lib/go"
GOTMPDIR=""
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
GOMOD=""
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build522995885=/tmp/go-build -gno-record-gcc-switches"

What did you do?

write some codes for example:

package main

import (
	"fmt"
	"log"
	"net"
)

func main() {
	conn, err := net.Dial("tcp", "127.0.0.1:80")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(conn)
}

and then GO111MODULE=on go build -x -i -o /tmp/dns_test test.go

What did you expect to see?

final result is &{{0xc0000b4080}}

What did you see instead?

I set GOPATH=/tmp/go to reproduce it

write the same codes, if I run go build -x -i -o test test.go , work fine, but if run GO111MODULE=on go build -x -i -o test test.go, report same thing
