Hi, all,
The grpc version is v1.0.0. The scenario is like this: I was using a
channel in a TRANSIENT_FAILURE state, and calling
channel.WaitStateForConnected in the background.
But something error happened in the cq, it returns an ERROR event (I don't
know the inside logic), and when destroy the cq, an assertion failed.
I think this may be a bug. Can anyone give me some hint?
Thanks,
Yihao
