I fixed the bug. It is due to I incidentally comment memcpy in
set_key() and commit to magnum-jumbo. Now it is:

[12:43:22 myrice] run $ ./john -te=1 -fo=xsha512-opencl -pla=1
OpenCL platform 1: AMD Accelerated Parallel Processing, 2 device(s).
Using device 0: Tahiti
Compilation log: LOOP UNROLL: pragma unroll (line 163)
    Unrolled as requested!
LOOP UNROLL: pragma unroll (line 168)
    Unrolled as requested!
LOOP UNROLL: pragma unroll (line 183)
    Unrolled as requested!

Optimal Group work Size = 128
Global work size = 2097152
Benchmarking: Mac OS X 10.7+ salted SHA-512 [OpenCL]... DONE
Many salts:     54176K c/s real, 1083M c/s virtual
Only one salt:  26214K c/s real, 41943K c/s virtual

Thanks
