    case wsrep::server_state::s_initializing:
        if (s_disconnected_disconnected == state_)
            return s_disconnected_initializing;
        else if (s_joining_sst == state_)
            return s_joining_initializing;
        else if (s_joining_initializing == state_)
            return s_joining_initializing; // continuation
        else
        {
            assert(0);
            return state_;
        }

asserts on startup when state_ is wsrep::reporter::s_joining_initialized.
(Note that input is wsrep::server_state::state, output is wsrep::reporter::state - we translate one enum into a different enum)

so somehow the reporter state got past initialized_ -> that happens only after it gets wsrep::server_state::s_initialized, but then somehow it gets wsrep::server_state::s_initializing again...
