// Test for select: Issue 2075
|
|
// 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.
