From src/or/connection.c, in `connection_handle_write_impl`: ``` if (getsockopt(conn->s, SOL_SOCKET, SO_ERROR, (void*)&e, &len) < 0) { log_warn(LD_BUG, "getsockopt() syscall failed?! Please report to tor-ops."); ``` I don't think we want people reporting this error to `tor-ops@torproject.org` (even if that address still works), but I don't know what to replace that with.
