[issue26868] Incorrect check for return value of PyModule_AddObject in _csv.c

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Testing returned value of PyModule_AddObject() is correct. This is a matter of style what to use: `if (...)`, `if (... == -1)` or `if (... < 0)`.

But the problem with a leak is more general. I have opened a discussion on Python-Dev: http://comments.gmane.org/gmane.comp.python.devel/157545 .
