What did you do?
I ran go test -v on the following code in pruner_test.go:
package prune
import (
"os"
"testing"
"github.com/spf13/afero"
)
func TestPruner_Prune(t *testing.T) {
testIO := []struct {
name string
fs afero.Fs
}{
{
name: "a simple test",
fs: func() afero.Fs {
fs := afero.NewMemMapFs()
_ = fs.Mkdir("/proc/2", os.ModeDir)
// Uncomment the next two lines prevent a compiler error
//_ = afero.WriteFile(fs, "/proc/2/stat", []byte("2 (tail) S 1 SKIP 12"), 0777)
//_ = fs.Remove("/proc/2/stat")
return fs
}(),
},
}
for _, test := range testIO {
t.Run(test.name, func(t *testing.T) {
})
}
}What did you expect to see?
=== RUN TestPruner_Prune
=== RUN TestPruner_Prune/a_simple_test
--- PASS: TestPruner_Prune (0.00s)
--- PASS: TestPruner_Prune/a_simple_test (0.00s)

Please file a bug report including a short program that triggers the error.

FAIL example.com/boom [build failed]
This compiler error can be avoided by uncommenting the two lines of commented-out code indicated in the source above. regardless, I believe the compiler shouldn't fail in either case.
