[Zope-dev] Test failure on integration-branch for Zope 2.11

[Christian Theune]

Hi,

I've started working on the integration of Zope 3.4 and ZODB 3.8 into
Zope 2.11.

I have a breaking test on ZClasses that I couldn't understand. I'd
appreciate any help.

The error is a max. recursion of an object that tries to load its state
and something goes off. Here's a part of the traceback:

File

    c2 = test2.C()
