The caller uses the value to size its memory allocation:
        gsize niov = rspamd_log_fill_iov(NULL, now, module, id, function, level_flags, message,
                                                                         mlen, rspamd_log);
        struct iovec *iov = g_alloca(sizeof(struct iovec) * niov);
and that faulted on aarch64.
