Hi,

Sorry for the delay. I had some mail problems.
I answer two message in the same e-mail

Yes

> Are you using an unmodified keyboard mode?
No. I swich to "AZERTY"

"Segmentation fault"

"Segmentation fault"

"Segmentation fault"

"Segmentation fault"

I built cygwin and john for this test.
Then I use the official binary&#61672; same problem

Here you are a similar problem, but not the same.

C:\...\john\john179j5\run>john --ext=3Dkeyboard --format=3Dnt2 =20
-session=3Dwin01 hash-10-2011a.txt
Loaded 1 password hash (NT v2 [SSE2i 12x])
guesses: 0  time: 0:00:00:12  c/s: 3984K  trying: 90ol/;oio - 90ol/;op-
Wait...

C:\...ows\1-Software\john\john179j5\run>john --restore=3Dwin01
Incorrect crash recovery file format: win01.rec

Then I try the original john.conf

   ~/john-1.7.9-jumbo-5/run
# ./john --ext=3DKeyboard --format=3Dnt2 -session=3Dwin01 hash-10-2011a.txt
Loaded 1 password hash (NT v2 [SSE2 4x])
guesses: 0  time: 0:00:00:05  c/s: 3100K  trying: dwdxdxse - dwdxdxsz
Session aborted

   ~/john-1.7.9-jumbo-5/run
# ./john --restore=3Dwin01
Loaded 1 password hash (NT v2 [SSE2 4x])
Segmentation fault (core dumped)


Conclusion,
-=09Problem appear during a restoring (sorry because I don=92t realize that=
)
-=09I don=92t know why appear SSE2 instead SSE2i in my compilation
(I use john-1.7.9-jumbo-5.tar.gz from your official site)
