This is very interesting. Purify sees nothing of the sort when run on
a simple test case on recent code, which should be mostly identical in
this area to krb5-1.3.4.
Does this only happen when you attempt to change the password of one
particular principal, or does it do so for all principals, including
brand new ones? Do you have password policies enabled? How many old
passwords do you keep, and have you changed that number changed
recently?
Also, what release of krb5 did you upgrade from?
