// child.c
max_cpu_time.rlim_cur = max_cpu_time.rlim_max = (rlim_t) ((_config->max_cpu_time + 1000) / 1000);
if (setrlimit(RLIMIT_CPU, &max_cpu_time) != 0) {
    CHILD_ERROR_EXIT(SETRLIMIT_FAILED);
}

setrlimit(RLIMIT_CPU, &max_cpu_time)

It will also exit in real execution time, and the if code block does not handle the case where real_time > max_cpu_time.

// runner.c
if (_config->max_cpu_time != UNLIMITED && _result->cpu_time > _config->max_cpu_time) {
