New submission from Xinmeng Xia <xi...@smail.nju.edu.cn>:
Running attached "test_zipfile.py" on Python 3.10 will lead to the following
error messages:
----------------------------------------------------------------------------------------------------
Exception ignored in: <generator object temp_dir at 0x7f13f30ff2e0>

However, if we run this program with os.system, the return value is 0 instead
of 256. 0 represent no fails in this running! This is obviously incorrect.
Reproduce:
=========================================
import os
scode = os.system('python310 test_zipfile.py')
print("The system code of this execution is:", scode)
=========================================
The expected output: "The system code of this execution is: 256"
The actual output: "The system code of this execution is: 0"
