New submission from kftse <kftse20031...@gmail.com>:
Test case:
try:
raise TypeError()
except TypeError or ValueError:
print("OK")
try:
raise ValueError()
except TypeError or ValueError:
print("OK")
Output:
(Python 3.9.0)
OK
OK
# seem to eventually lead to segmentation fault elsewhere
(Python 3.8.0)
OK
Traceback (most recent call last):
File "test.py", line 7, in <module>
raise ValueError()
ValueError
I understand that this code is incorrect syntax for exception.
The awkward behavior is that the interpreter accepted this syntax and the
output being correct in some case, or even in both cases, but seem to
eventually lead to segmentation fault elsewhere.
