We are seeing a core dump whenever CouchBase connection attempt fails for the first time and we try to reconnect.
This is a case when the client comes up before the Couchbase server.

I've fixed one usage of addrinfo struct, is it possible to get minimal script to reproduce the issue, or maybe you can grab the patch, apply and verify it?

Ok, I've found the issue, and they are right, rebuild instance will of course fix the issue. So there is workaround. I'm working on proper solution.

There is some state which isn't reset on the second connection attempt: like instance->backup_idx and instance->configuration_callback_last. I'm working on the fix now
