Lib/test/crashers/nasty_eq_vs_dict.py does crash Python because of an infinite loop in the dictionary lookup. The script modifies the dictionary at each lookup, whereas Python tries a new lookup each time that the dictionary is modified. I proposed to make the lookup fail with a RuntimeError if the dictionary has been modified during a lookup. It should not occur if you are not doing something evil.
