pull up r18748 from trunk

 ticket: new
 subject: don't confuse profile iterator in 425 princ conversion
 target_version: 1.6
 tags: pullup

 The profile iterator code hangs onto and uses the list of names passed
 in.  The krb5_425_conv_principal code reuses that array when the
 iterator may still be used.

 * conv_princ.c (krb5_425_conv_principal): Use separate name arrays for
 the iterator and the v4_realm lookup that may be done inside the
 iteration loop.

ticket: 4534
version_fixed: 1.6
