If we fail to generate an extrainfo (can that happen?) we go on generating a routerinfo, but later in router_rebuild_descriptor() we do: ``` if (options->BridgeRelay) { /* Bridges shouldn't be able to send their descriptors unencrypted, anyway, since they don't have a DirPort, and always connect to the bridge authority anonymously. But just in case they somehow think of sending them on an unencrypted connection, don't allow them to try. */ ri->cache_info.send_unencrypted = ei->cache_info.send_unencrypted = 0; } else { ri->cache_info.send_unencrypted = ei->cache_info.send_unencrypted = 1; } ``` note the unconditional assignment to a field of ei.
