Memory leak or programing error

[Greg Hudson]

The KRB5RCACHETYPE=none leaks were fixed by Ken Raeburn in r22417 which
should make it to release in 1.7.1.

A brief look at the spnego code suggests those memory leaks are still
present in the trunk, possibly along with other leaks.  I will work on
cleaning this up; please send me (private mail is fine) the base64 files
you are using.

Thanks for the investigation work you've done.
