openssh unix dev - Sep 2010 - AuthorizedKeysFile in Match block causes seg. fault

OpenSSH 5.6p1 will attempt to free static storage and seg. fault if
AuthorizedKeysFile is used within a Match block without any global
specification of that option.  A simple fix is to xstrdup the defined
pathnames as in the attached patch.
