Hm, it would have been hard to see that just from the time the test
took to fail, compared to the time of a successful test.

But then, some algorithms might need a new function to init some
buffers for all the (up to) MAX_KEYS_PER_CRYPT passwords...

Yes, I also noted that crypt_all was using MAX_KEYS_PER_CRYPT instead
of count in the first for(...) loop.

Yes, the patch works for me as well, thanks.
