Actually if you do inlining you end up with the cast happening to &node in this
case. Your reduced testcase is undefined because nothing can change y.prev
between the constructor and the call to back so you end up with accessing a
Node_base via a Node and there is no such data there.  

The original testcase might not be, I have to look into the preprocessed source
and the tree dumps to figure out if you reduced the testcase too far or really
the original testcase is just undefined.
