This time, using the jumbo patch, subsequent executions did NOT lead to
new guesses, as it should be. :)

Conclusion:


Wordlist out of the LM pot with "--show | cut -d: -f2 > wordlist"
(unsorted, not unique, with unfinished "passwords" (unknown letters
presented by "?"))

wordlist length: 2227 lines
smooth would be: 1628 lines
(with "tr A-Z a-z < wordlist | sort -u > smooth)

But in order to be comparable to the original situation, I did not use
"smooth" but "wordlist" in all runs.
The state before the first run was:
-same wordlist and passwd files
-no john.pot, john.log, john.rec in the directory

"john-1-7-2" with "john-1.7.2-ntlm-alainesp-4.diff"
First run: 1459 guesses
Second run: 65 guesses
Third run: 0 guesses
Some more: 0 guesses

"john-1-7-2" with "john-1.7.2-all-2.diff.gz"
First run: 1546 guesses
Second run: 0 guesses
Some more: 0 guesses

There may be really a bug... interesting is also, that the jumbo patch
lead to 22 guesses in addition to the sum of the first and second run
with the ntlm patch.

I use an aged P4 2 GHz for testing... And another instance of john is
running on the LM hashes (and some calculation for my thesis too)
So the time is not very meaningful...

Thank you and kind regards
