Subject: self test failed with OpenCL on a GPU

When I use john with '--format=sha512crypt-opencl', it says "Self test
failed (get_hash[0](0))". If I specify '--devices=cpu', it works, but it
does not work if I specify GPU or if I leave off the '--devices'.
Is this a problem in my setup? Or is it a bug?

P.S. Complete log:

[benji@...alhost run]$ ./john shadow --format=sha512crypt-opencl
--device=0 --wordlist=/home/benji/Downloads/passlists/total.txt
Device 0: Cayman
Local worksize (LWS) 256, global worksize (GWS) 6144
Loaded 5 password hashes with 5 different salts (sha512crypt-opencl,
crypt(3) $6$ [SHA512 OpenCL])
Self test failed (get_hash[0](0))

Thanks,

Benji
