The attached example works in the __add__ and __getattribute__ cases on CPython, but fails in the __getattr__ case. All three cases work as the semantics say they should on Jython, IronPython and PyPy. It's admittedly an obscure use case. There is no reason that __getattr__ should behave differently. The behavior of __add__ and __getattribute__ is the "correct" one, according to the rule that special methods are bound (with __get__) before they are called.

It's the issue for python 3.0 too

Here is a patch for trunk and 2.5 version. It also contains a fix for another crasher (see the tests). I only tested the 2.5 patch, because I don't have the tools for the trunk installed.

Here is another patch, for Python 2.4, which contains only the security fix. Benjamin, will you also commit these backports?

Backported to 2.4 in r67250 and 2.5 in r67251.
