This little script 'ctypes-leak.py' leaks memory:
"""
import gc
from ctypes import *
PROTO = WINFUNCTYPE(None)
class Test(object):
def func(self):
pass
def __init__(self):
self.v = PROTO(self.func)
while 1:
try:
Test()
gc.collect()
except KeyboardInterrupt:
print len([x for x in gc.get_objects()
if isinstance(x, Test)])
"""
The cause is that patch related to issue #2682; it leaks since rev. 62481 (in trunk) and rev. 62484 (in py3k).
I have not yet been able to find the cause of the leak.

CThunkObject is not registered correctly with the cycle GC. The attached patch, against trunk, fixes the issue. |
