What did you do?

func main() {
	l := []int{1, 2, 3}
	for i, v := range l {
		println(&i, &v)
	}
}

result is:
0xc00004c718 0xc00004c710
0xc00004c718 0xc00004c710
0xc00004c718 0xc00004c710

func main() {
	l := []int{1, 2, 3}
	for i, v := range l {
		fmt.Println(&i, &v)
	}
}

result is:
0xc000096010 0xc000096008
0xc000096030 0xc000096018
0xc000096040 0xc000096038

func main() {
	l := []int{1, 2, 3}
	for i, v := range l {
		println(&i, &v)
		fmt.Println(&i, &v)
	}
}

result is:
0xc0000120a0 0xc000012098
0xc0000120a0 0xc000012098
0xc0000120c0 0xc0000120a8
0xc0000120c0 0xc0000120a8
0xc0000120d0 0xc0000120c8
0xc0000120d0 0xc0000120c8

What did you see happen?

result is different between with println(&i, &v) & fmt.Println(&i, &v)

What did you expect to see?

0xc000096010 0xc000096008
0xc000096030 0xc000096018
0xc000096040 0xc000096038

fmt.Println causes arguments to escape to the heap, see #19720 which is a duplicate of #8618
