Comment (by arma):

 This looks like a fun one:

 In config.c:3538, in options_validate(), we have
 {{{
     if (circuit_build_times_disabled(options)) {
       severity = LOG_INFO;
     }
 }}}

 In circuit_build_times_disabled(), we have
 {{{
     int consensus_disabled = networkstatus_get_param(NULL, "cbtdisabled",
                                                      0, 0, 1);
 }}}

 In networkstatus_get_param(), we have
 {{{
   if (!ns) /* if they pass in null, go find it ourselves */
     ns = networkstatus_get_latest_consensus();
 }}}

 In networkstatus_get_latest_consensus(), we have
 {{{
   if (we_use_microdescriptors_for_circuits(get_options()))
 }}}

 And it's that get_options() that screws us -- it goes to fetch the global
 options value, and there isn't one yet since we're still in the middle of
 validating it.
