rand.Intn should not return a fixed number sequence #4509
Description
by nanjunjie:
From document of rand.Intn:
Intn returns, as an int, a non-negative pseudo-random number in [0,n). It panics if n
<= 0.
I found it always returns a fixed number sequence. For example on my machine, the
sequence for Intn(10) is: :8, 6, 6, 7, 0...
What steps will reproduce the problem?
Source:
package main
import (
"fmt"
"math/rand"
)
func main() {
fmt.Println(rand.Intn(10))
}

What is the expected output?
It should return a random number.
What do you see instead?
On play.golang.org, the output is always 1 for each run. On my machine, the output is
always 8.
Which operating system are you using?
Ubuntu 12.04
Which version are you using? (run 'go version')
