runtime: program with deadlock doesn't fail if use -race flag

[nizsheanez]

Go version: 1.8.3
OS: Mac

Program:

package main

func main() {
	ch1 := make(chan int)
	<-ch1
}

if run with go run deadlock.go see: fatal error: all goroutines are asleep - deadlock!

if run with go run -race deadlock.go program never finish

Is it expected behavior?
Does it make sense to improve deadlock detector to be aware about race detector?

This is a duplicate of a very old issue.

Sorry, i didn't find it. Let's close then.

Perhaps #5475?

#5475 is slightly different, and is closed anyhow.

I also think this was reported before, but I can't find the issue, so until it turns up lets make this one the issue for the problem.

I think #5477 is what you were looking for, was FrozenDueToAge (and it's duplicate #5476)
