[Python-Dev] funny leak (original) (raw)

OK, there's no leaking memory here, but there is a leaking refcount: the refcount on the int 0 keeps going up. The compiler has leaked references to little integers before, but offhand I don't recall the details.

----- old stuff ----- OK, this program leaks a reference each time around; probably a missing decref in the compiler:

source = """
def conjoin(gs): def gen(): gs # unbreakable cycle gen # unless one is commented out """

def one(): exec source in {}

import sys, gc lastrc = 0 while 1: one() gc.collect() thisrc = sys.gettotalrefcount() print thisrc - lastrc, lastrc = thisrc
