func clos(x func()) func() {
	f := func() {
		print("")
		x() // This statement crashed, because the partial call was allocated on the old stack.
	}
	// Grow stack so that partial call x becomes invalid if allocated on stack.
	growstack(10000)
	c := make(chan bool)
	// Spoil the previous stack segment.
	go func() {
		c <- true
	}()
	<-c
	return f
