same salt bug in rar not detected

TS says all is clear, since jtr says it cracked all items. However, not all were cracked, and there is issues where jtr was thinking there were dupe salts when there should not be.
To work around this (or possibly show OTHER issues), I will re-run JtR after each test, simply to make sure it says no passwords are left.
NOTE This MAY be a problem for formats that are not precise (CRC32, etc). But I can think of no other way to detect this type bug, and it is POSSIBLE that other formats also list that they cracked X number of hashes when in actually they did not.

Here is a run showing the 'bug' (i.e. prior to adding hash of buffer to the salt)
$ ../run/john -w=pw30.dic rar_tst.in -pot=tst.pot -form=rar
Loaded 130 password hashes with 19 different salts (rar, RAR3 [SHA1 AES 32/64])
Will run 8 OpenMP threads

Use the "--show" option to display all of the cracked passwords reliably

19 password hashes cracked, 111 left
So it appears that --show SHOULD catch this issue. I have to re-think logic.

Ok, added this code (for testing)
} elsif ($ret_val == 0) {
my $str = sprintf("form=%-28.28s guesses: %4.4s $crack_xx[3] $crack_xx[4] [PASSED]\n", $ar[4], $orig_crack_cnt);
ScreenOutSemi($str);
+ if ($orig_crack_cnt != $orig_show_cnt) {

+ ScreenOutAlways($str);
}
} else {here are the results (note, did not do FULL formats).

All things were tested, and the dyna, crc and lm hashes ALREADY had (-show1502), etc in them. This is just a final check. Before showing [PASSED], we check to see if shown count is different than guess count. If it is, we then validate that there is not a (-show###) value. If there is and it passes, we still show [PASSED]. Otherwise we show the message like above.
