svn rev #21924: trunk/src/lib/krb5/krb/

[ghudson@MIT.EDU]

Commit By: ghudson
Log Message:
ticket: 6379
subject: Fix possible free of uninitialized value in walk_rtree
tags: pullup
target_version: 1.7

In rtree_hier_realms, if the first rtree_hier_tweens call failed, the
cleanup handler would free stweens which had not been initialized.
Initialize ctweens and stweens to NULL in the variable declarations to
make the cleanup handler safe.
