Is there any problem with my assumption that the atomic increments are safe here? https://play.golang.org/p/WpXIcgj1_lQ

shared_atomic_increments.go

package main

import (
	"fmt"
	"sync/atomic"
	"time"
)

type Foo struct {
	I *int64
}

func main() {

	var counter int64

	a := Foo{&counter}
	b := Foo{&counter}
	c := Foo{&counter}

	go func() {
		for {
			atomic.AddInt64(a.I, 1)
		}
	}()
	go func() {
		for {
			atomic.AddInt64(b.I, 1)
		}
	}()
	go func() {
		for {
			atomic.AddInt64(c.I, 1)
		}
	}()

	for i := 0; i < 5; i++ {
		time.Sleep(time.Millisecond * 100)
		v := atomic.LoadInt64(&counter)
		atomic.StoreInt64(&counter, 0)
		fmt.Printf("%15d\n", v)
	}
}
