Really? With overlapping list nodes? Common?! Did you miss that the bug
could be exposed only when two nodes overlap like this:

node1:  |next|prev|
node2:       |next|prev|

I think it's rather unlikely that this bug will show itself in real-life
code, so chances are high nobody but Till noticed it yet.
