??

[juyik, 2014/03/01 00:21:57]

 This has been fixed in my newer patch.

+  stats->connection_client_created = (mcs_client_.get() != NULL);
+  stats->connection_state = MCSClient::GetStateString(mcs_client_->state());

[fgorski, 2014/02/28 19:52:47]

can MCSClient be NULL here?

[juyik, 2014/03/01 00:21:57]

Fixed in my newer patch.
