Subject: Re: SSE bug still there in Jumbo-5-RC6++

I get a crash on OpenLDAPS.  Same type.  Only MMX/SSE builds (from 
cygwin/mingw).  It also only crashes on -test    not 
on -test -format=openssha   The format_init has been commented out in john.c 
for a couple of releases, but this is the same type of bug, and really needs 
to be found.

Jim.

Jumbo-5-RC6++ works great on MacOS X for 64-bit build.  No issues.

On MacOS X using the sse2 build, I get the following error for NSLDAP 
benchmarking:

Benchmarking: Netscape LDAP SHA SSE2 [SHA-1]... FAILED (get_hash[0](3))

Now this only occurs when running ./john -test.  If  I run 
./john -test -format:nsldap, it works correctly:

../run/john -test -format:nsldap
Benchmarking: Netscape LDAP SHA SSE2 [SHA-1]... DONE
Raw: 7837K c/s real, 7837K c/s virtual

Not sure why.
