What did you do?

import (
	"fmt"
	"testing"
)

func makeRace() {
	var x int
	c := make(chan bool)
	go func() {
		x = 1
		c <- true
	}()
	fmt.Println(x)
	<-c
}

func TestFoo(t *testing.T) {
	makeRace()
}

when running go test ./... -v -race :

PS C:\Users\kamal\Desktop\testmaps> go test ./... -v -race
?       testmaps        [no test files]
exit status 0xc0000139
FAIL    testmaps/cache  0.172s
FAIL

What did you see happen?

also i notice that i have the same exit error even if there is no race at all, just adding the -race flag break everything

What did you expect to see?

since i use -v, i should see logs of where the race happened
