Here's an example of hash-attack.patch finding an on-purpose programming error (hashing all objects to the same value): http://stackoverflow.com/questions/4865325/counting-collisions-in-a-python-dictionary (see the second example on the page for @Winston Ewert's solution) With the patch you get: Traceback (most recent call last): File "testcollisons.py", line 20, in <module> d[o] = 1 KeyError: 'too many hash collisions'
