This is a bug in IronPython, here's the simple repro: class C: pass import weakref weakref.ref(C) OldClass just needs to have an IWeakReferencable implementation added to it. Looks like this is new in 2.7.0 and I'm guessing something in 2.7.1 now depends upon it. Maybe there just wasn't a test case for it or we have it disabled in the IronPython dir. _______________________________________________ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
