// A bug in select corrupts channel queues of failed cases
// if there are multiple waiters on those channels and the
// select is the last in the queue. If further waits are made
// on the channel without draining it first then those waiters
// will never wake up. In the code below c1 is such a channel.
package main
func main() {
c1 := make(chan bool)
c2 := make(chan bool)
c3 := make(chan bool)
go func() { <-c1 }()
go func() {
select {
case <-c1:
panic("dummy")
case <-c2:
c3 <- true
}
<-c1
}()
go func() { c2 <- true }()
<-c3
c1 <- true
c1 <- true
}
