            Bug ID: 205834
           Summary: rtadvd: accessing freed struct
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: cherepan at mccme.ru

The problem is in the rm_ifinfo function. If the ifi structure is freed at
https://svnweb.freebsd.org/base/head/usr.sbin/rtadvd/config.c?revision=289750&view=markup#l237
it is then accessed at
https://svnweb.freebsd.org/base/head/usr.sbin/rtadvd/config.c?revision=289750&view=markup#l246
and further.
