Self-contained example that fails for me on 32-bit OS X.
class Integer(int):
 def __new__(cls, value, base=10, indirect=False):
 try:
 obj = int.__new__(cls, value, base)
 except TypeError:
 obj = int.__new__(cls, value)
 return obj
 def __init__(self, value, base=10, indirect=False):
 self.indirect = indirect
integers = []
for i in range(1000):
 integer = Integer(b'0')
 integers.append(integer)
for integer in integers:
 assert int(integer) == 0
