This helped, but there's too many other factors across the commit
(compilation failures, etc.) to really zoom in properly -- at my
levels of git skill and cycles right now, anyway.  If I ignore 'Self
test failed (get_hash[0](3))' errors and bisect accordingly, I get too
many hits to be useful (as far as I can tell):

There are only 'skip'ped commits left to test.
The first bad commit could be any of:

We cannot bisect more!
bisect run cannot continue any more

I also got the following error on recent makes, but do not know if
it's relevant or not:

DES_std.c: In function ‘DES_std_set_key’:
DES_std.c:637:17: warning: array subscript is above array bounds
[-Warray-bounds]
   while (DES_key[i++]) k += 2;

So I'm stuck on how to move past my 'Failed Copy data to gpu' error.
The consequence is that I can only use one CPU core to send candidate
passwords to descrypt-opencl.

Is anyone else seeing this?
