I would propose to prepend the app/lua/lua code with

#if defined(__AVR_ARCH__) && !define(_OPTIMIZE__)
int main(void)
    unsigned long baud = 115200;

    /* Initialize the console. */
    NutRegisterDevice(&DEV_CONSOLE, 0, 0);
    freopen(DEV_CONSOLE.dev_name, "w", stdout);
    freopen(DEV_CONSOLE.dev_name, "w", stderr);
    freopen(DEV_CONSOLE.dev_name, "r", stdin);
    _ioctl(_fileno(stdin), UART_SETSPEED, &baud);

    /* Display banner. */
    puts("\nPlease compile the LUA example with optimization enabled\n");

(original code)
