New submission from tongxiaoge <shixuantong at huawei.com>:

I have reproduced this problem in the latest versions of Python 3.8.11 and 3.9.6. Python 3.8.5 does not have this problem, other versions are not tested. The failure log is as follows：

What is the reason for this? and is there a plan to fix it?
