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

go version go1.14.6 gccgo (Debian 10.2.0-7) 10.2.0 linux/amd64

and

go version go1.15rc2 gccgo (Debian 20200809-1) 11.0.0 20200809 (experimental) [master revision fb9e3f79464:8ad857c7881:94d4f4387de8264ee289cf71f692d59ca6ac36f8] linux/amd64

Does this issue reproduce with the latest release?

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

What did you do?

$ ls $GOPATH/src/golang.org/x/net/http/httpguts
guts.go  httplex.go  httplex_test.go

$ export GO111MODULE=off

$ cat test.go
package main

import (
        _ "golang.org/x/net/http/httpguts"
)

func main() {}

$ go run test.go

What did you expect to see?

go run test.go without error

What did you see instead?

go build golang.org/x/net/http/httpguts: no Go files in /usr/src/golang.org/x/net/http/httpguts

It happens with GOPATH, and GO111MODULE=off, and without vendor dir.

I'm not sure what is happening here, but it must have something to do with the fact that golang.org/x/net/http/httpguts is vendored into the standard library.

Probably it's same as #41368

I just found someone is trying to build containerd with gollvm, then I double checked the gccgo build result. We build go packages with gccgo on ppc64 in Debian. https://buildd.debian.org/status/logs.php?pkg=containerd&arch=ppc64

libgo: don't put golang.org packages in zstdpkglist.go

This ensures that internal/goroot.IsStandardPackage does not treat
golang.org packages as being in the standard library.

For golang/go#41368
Fixes golang/go#41499
