    The whole point of a doubly linked list is to avoid the nonsense of list reversal.

    If you want to traverse it backwards, you just start at tail, and follow all the node->prev until you get to NULL.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
