It will only occur on  python 2.5 or later (due to PEP 353) when 
sizeof(Py_ssize_t)  != sizeof (int).

This is effectively almost all 64bit python2.5s (exception is ILP64 - 
can't think of example of this).

btw, building from svn head (including dependencies) the code posted in 
https://bugs.launchpad.net/ubuntu/+source/zodb/+bug/165287 works correctly.

Unfortunately, I do get the  following error when running the tests:
