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

go version devel +d11df8baa8 Sun Apr 22 22:32:11 2018 +0000 windows/amd64

Does this issue reproduce with the latest release?

Yes

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

Windows7 64bit

What did you do?

package main

import (
	"fmt"
	"os"
)

func main() {
	fmt.Println(os.Stat("*.go"))
}

What did you expect to see?

return error

What did you see instead?

not return error

This is broken in e83601b, I guess. FindFirstFile resolve wildcard. So if *.go exists, os.Stat("*.go") doesn not fail.

This wildcard must no be accepted.
