http://www.python.org/sf/1202533 has a potential fix for the infinite_rec_*.py crashers. PyObject_Call() basically needs a recursion check. But there were some issues with PyErr_NormalizeException() blowing up while trying to normalize the exception, that also needs to watch out for hitting the recursion limit and returning a RuntimeError that does not need normalization itself.
http://www.python.org/sf/1377858 has a patch for weakref_in_del.py . Turns out if you create a new weakref in a __del__ for self the weakref is never notified that self is gone and it no longer has a valid weakref to anything. Added a check after __del__ is called to make sure that if any weakrefs were created that they get cleared.
http://www.python.org/sf/1303614 is a discussion currently between Armin and I on how to handle del___dict__.py . Looks like more careful reference counting is needed, but Armin is worried about a performance hit. There is also a patch there to fix loosing_dict_ref.py .
dangerous_subclassing.py, modify_dict_attr.py, and nasty_eq_vs_dict.py I have not gotten to yet. I am ignoring bogus_code_obj.py, gc_inspection.py, and recursive_call.py since they either require setting the recursion depth higher or involve an extension module.
