Ok I wasn't completely crazy about cpython having issues with this

test/tests/cpython_oldstyle_getattr_crash.py

+# This segfaults under python-dbg
+# (In a release build it "works" since the use-after-free happens without penalty.)
+
+class C:
+    def __getattr__(self, attr):
+        del self
+        print "C.__getattr__", attr
+        del D.__get__
+        raise AttributeError()
+
+class D(object):
+    __get__ = C()
+
+class E(object):
+    x = D()
+
+try:
+    print E().x
+except Exception as e:
+    print e
