What steps will reproduce the problem?

main.go:
package main

import (
        "fmt";
        "runtime";
        )

func main() {
        log("line # 9")
        fmt.Println("line # 10")
        log("line # 11")
        fmt.Println("line # 12")
}


func log(message string){
        _, file, line, ok := runtime.Caller(1)
        if !ok { fmt.Println("some error"); return }
        fmt.Printf("%s:%d %s\n", file, line, message)
}

What is the expected output?
./main.out
/home/alexni/workspace/go/test/main.go:9 line # 9
line # 10
/home/alexni/workspace/go/test/main.go:11 line # 11
line # 12

What do you see instead?
./main.out
/home/alexni/workspace/go/test/main.go:10 line # 9
line # 10                            ^^^^      
/home/alexni/workspace/go/test/main.go:12 line # 11
line # 12                            ^^^^


What is your $GOOS?  $GOARCH?
GOARCH=amd64
GOOS=linux
