I fixed your example with some explanatory comments:
https://play.golang.org/p/zwt78CPwxk_o
package main
import ( "fmt" )
func main() {
Af(5)
}
func Af ( N int) {
//Initialize outer array, you get an array of 25 nil arrays
M := make( [][]uint16, N*N,N*N)
for y:=0; y< N; y++ {
// Initi

The above two will not w
Here's the snippet I'm trying to run
package main
import ( "fmt" )
func main() {
Af(5)
}
func Af ( N int) {
//var M = new([N][N]uint16) !compiler error
//var M = make([N][N]uint16)!compiler error
//var M = make([][]uint16, N*N) ## run-time error
// run-time error
M := make( [][]u
binary.Read can't set unexported fields, right?
But my structs are defined in C, and I can't make all C source code using
capital fields..
What could I do?

Ah, yes, it is number of runs.
What a silly question. :)

You need the -benchmem flag to get a report of allocations:
$ go test -bench=. -benchmem
goos: darwin
goarch: amd64
BenchmarkTestSleep_2000-4 1 2005447537 ns/op 456 B/op
3 allocs/op
BenchmarkTestSleep_1000-4 1 1001627153 ns/op 64 B/op
1 allocs/op
BenchmarkT
The first number in the benchmark output provides the number of iterations
the test is run. It has nothing to do with the number of allocations. The
default benchmark time is 1 second, explaining the number of iterations you
are observing. You can change the time using the -benchtime flag.

The following benchmark is modified from
https://github.com/golang/go/issues/30802
package main
import (
"testing"
"time"
)
func SleepTest(milliseconds time.Duration) {
time.Sleep(time.Millisecond * milliseconds)
}
func BenchmarkTestSleep_2000(b *testing.B) {
for i := 0; i < b.

For a simple parent/child module relationship this seems to work, since the
'replace' work-around is in the parent go.mod.
But when the childA depends on childB, then the 'replace' directive in
