memory leak

[hxsnow10]

my python version is 2.7,5 aahocorasick.so is copyed from git.

#encoding=utf-8`
import ahocorasick

class AC(object):

    def __init__(self, keys):
        self.keys=keys
        A = ahocorasick.Automaton()
        for key in keys:
            A.add_word(key, key)
        A.make_automaton()
        self.A=A

    def get_locss(self, text):
        if not self.keys: return []
        locss=[[key,end_idx-len(key)+1,end_idx+1] for end_idx, key in self.A.iter(text)]
        return locss

if __name__=="__main__":
    a=AC(["你","wo "])
    s="你妹啊。。。。"
    for i in range(100000000000):
        a.get_locss(s)

Test this script, i get

@hxsnow10 In order to check if there are any memory leaks you should run the python's garbage collector.
