Is the test written properly? I find this function suspicious. Everything after
the while(1) loop is dead code...

void *countTaskAsync(void *ignored)
{
  int i=0;
  int type,state;

  pthread_setcancelstate(PTHREAD_CANCEL_ENABLE, &type);
  pthread_setcanceltype(PTHREAD_CANCEL_ASYNCHRONOUS, &state);
  pthread_cleanup_push(countTask_cancel_handler, NULL);
  while (1) {
    printf("countTaskAsync: elapsed time (second): %2d\n", i++ );
    sleep(1);
  }
  countTask_handler = false;
  pthread_cleanup_pop(1);
  if ( countTask_handler == false ){
    puts("countTask_cancel_handler not executed");
    rtems_test_exit(0);
  }
}
