What did you do?

For codes

func main() {
	var a64 atomic.Int64
	fmt.Println(unsafe.Alignof(a64))
}

With compile GOOS=linux GOARCH=386 go build tt.go

Got the output error

# command-line-arguments
./test.go:8:28: internal compiler error: got 4 from types2, but want 8

Please file a bug report including a short program that triggers the error.
