rt_thread_delete删除线程引起断言

Hi，rtt os运行在多核上，现在每个core都运行1个线程，等待5s后，调用rt_thread_delete删除每个核上创建的线程，遇到了下面的错误：
```
smp test start,need to wait 5s!
smp bind pass
(rt_object_get_type(&timer->parent) == RT_Object_Class_Timer) assertion failed at function:rt_timer_control, line number:463 
kernel panic on CPU 2 at /home/kunlun/aichip/new/rt-thread/src/kservice.c+1445: assert

经分析，似乎是delete后资源已经释放了，可是线程正在运行，code走到这里的时候必然会出现断言错误？（代码见附件）
 
请问是不是接口使用不对？还是rtt os有不足的地方？
