OK

No, no. This is happening with cython-devel.

BTW, I switched to the revision above (a few commits away for latest
release), and all seems to work.

Revision: 1393
Branch: default
Author: Stefan Behnel <scoder@...>  2008-11-26 18:00:35
Committer: Stefan Behnel <scoder@...>  2008-11-26 18:00:35
Parent: 1392:a53116f21261 (fixed typo)
Child:  1394:71d8a06957eb (make TupleNode and ListNode a NewTempExprNode)

    let types inherit from object to work around hashing problems

Yes, and that is the very commit that broke a lot of things  It just 
doesn't show up because the testsuite is not complete, and it only 
strikes in special circumstances.

I would also consider that revision safe. But I agree that for releasing
software, the latest official Cython release is the safest bet.
