bad argument #2 to '__newindex' (not a number in proper range)

[yangyongzhen]

is go-lua can only run in 64bit machine?
when i run my lua script on ubuntu 64 bit, it works ok( lua test.lua), and i run my golang code using go run main.go,int works ok too,
but when i just cross compile the same golang code using GOOS=linux GOARCH=arm GOARM=7 go build main.go
error occured,
i hope to use go-lua on my 32bit arm board,

panic: runtime error: test.lua:34: bad argument #2 to '__newindex' (not a number in proper range)
goroutine 1 [running]:
main.main()
/mnt/hgfs/b503/gopath/src/golua/main.go:11 +0xa0

the 34 line is string.format("%012d",34567890121111)
why? is go-lua can only run in 64bit machine?

Here's my test：
package main
import "github.com/Shopify/go-lua"
import "fmt"
var arg1 = 1
var arg2 = 2
func add(x, y int) int {
fmt.Printf("this is go func add\n")
return x + y
}

var luatestGofunc0 = func(l *lua.State) int {
fmt.Printf("this is a go func-0 called by lua script!\n")
top := l.Top()
fmt.Printf("top:%d\n", top)
a0 := l.ToUserData(0)
a1 := l.ToUserData(1)
a2 := l.ToUserData(2)
fmt.Printf("ao,a1,a2=%#v,%#v,%#v\n", a0, a1, a2)
return 2
}

func main() {
fmt.Printf("hello golang,test lua script...\n")
l := lua.NewState()
l.Register("LtestGofunc0", luatestGofunc0)
l.Register("LtestGofunc1", func(l *lua.State) int {
fmt.Printf("this is a go func 1...\n")
return 0
})
lua.OpenLibraries(l)
if err := lua.DoFile(l, "test1.lua"); err != nil {
panic(err)
}
}

bellow is test1.lua:
this is a lua script demo:

print("this is CONNECT,"..ip..port)
