I have make a test in version go1.11.4 windows/amd64:
func main() {
const SZ = 65536
var time_array [SZ]float64
c := make(chan os.Signal)
signal.Notify(c, os.Interrupt, syscall.SIGTERM)
go func() {
<-c
fmt.Printf("You pressed ctrl + C. User interrupted infinite loop.")
fmt.Printf("%v ", time_array); // <=== all zeroes printed.
os.Exit(0)
}()
i := 0
for i < SZ {
time_array[i] = 1
fmt.Printf("%f bps ", time_array[i]) //<=== value printed is correct.
time.Sleep(time.Second * 1)
i++
}
}
the result is :
1.000000 bps 1.000000 bps 1.000000 bps 1.000000 bps 1.000000 bps 1.000000 bps
1.000000 bps 1.000000 bps 1.000000 bps You pressed ctrl + C. User interrupted
infinite loop.[1 1 1 1 1 1
1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0...0]
so, I think that others wrong in your code.
