I just decreased its PLAINTEXT_LENGTH to 15 (like the opencl format) and
this works fine. However, it still intermittently fails self-test at
cmp_all(1) - something is not initialized correctly. When it passes
self-test, it passes TS too.
If I test xsha512-cuda right before it, it will fail:

Also, if I just run a --test with xsha512-cuda right before pwsafe, it
will also fail:

magnum@...l:test [master]$ ../run/john -t -fo:pwsafe-cuda
Benchmarking: Password Safe SHA-256 [CUDA]... FAILED (cmp_all(1))
If I do not, it works fine:
magnum@...l:test [master]$ ../run/john -t -fo:pwsafe-cuda

Lukas, if you can reproduce the above I bet you can nail it.
BTW I also moved the endian-swap out of crypt_all() and into get_salt()
for good measure (and same fix for the opencl format).
