What did you do?
Ran this program with go run stat_test.go.
https://gist.github.com/kr/a337f4a7bda21d44048d7d83d52e5456
(It doesn't compile on play.golang.org because it needs 1.6rc1).
What did you expect to see?
FileInfo, same as from os.Stat(runtime.GOROOT()) in the commented line in the testcase gist linked above.
What did you see instead?
open /usr/local/go: invalid argument
