A reproducer was given in
<https://issues.guix.gnu.org/25752#0>:

guix environment --ad-hoc go -- bash -c 'export t=$(mktemp -d); cd
$t && export GOPATH=$(pwd) GOBIN=$(pwd)/bin && go install cmd/go; cd
&& rm -rf $t'

guix environment --ad-hoc go -- bash -c 'export t=$(mktemp -d); cd
$t && export GOPATH=$(pwd) GOBIN=$(pwd)/bin && go list -f '\''{{join
.Deps "\n"}}'\'' cmd/go | xargs -n1 go list -f '\''{{if
.Stale}}{{.ImportPath}}: {{.StaleReason}}{{end}}'\''; cd && rm -rf $t'

I don't know if this reproducer still works/fails.

Greetings,
Maxime.
