  - 'deny-answer-aliases' is a little-used feature intended
    to help recursive server operators protect end users
    against DNS rebinding attacks, a potential method of
    circumventing the security model used by client
    browsers. However, a defect in this feature makes it
    easy, when the feature is in use, to experience an
    assertion failure in name.c. Affects BIND

has attempted to automatically clean and format it as much as possible
