And how to interpret the conflicting messages for the following program?
package main
type T int
const N = 1<<12
var i = N - 1
func main() {
var r = make([]T, N) // make([]T, N) does not escape
println(r[i])
var r1 = g() // make([]T, N) does not escape
println(r1[i])
}
func g() []T {
var ts = make([]T, N) // make([]T, N) escapes to heap
return ts
}
