New submission from Cliff Cordeiro <cliff.corde...@gmail.com>:
This class is not collected by the gc without a custom __del__ method to del or
assign None to self.fn:
import gc
class Leak:
def __init__(self):
self.fn = self.x
def x(self):
pass
gc.set_debug(gc.DEBUG_SAVEALL)
l = Leak()
del l
gc.collect()
for item in gc.garbage:
print(item)
