New submission from Oren Milman:
The following code causes an assertion failure:
class BadInt(int):
def __abs__(self):
return None
import random
random.seed(BadInt())
this is because random_seed() (in Modules/_randommodule.c) assumes that
PyNumber_Absolute() returned an int, and so it passes it to _PyLong_NumBits(),
which asserts it received an int.
what should we do in such a case?
should we raise an exception? (the docs don't mention abs() in case the seed is
an int - https://docs.python.org/3.7/library/random.html#random.seed)
