So, I upgraded it to latest:
Platform #1 name: AMD Accelerated Parallel Processing
Platform version: OpenCL 1.2 AMD-APP (923.1)
Device #0 name: Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
Device vendor: GenuineIntel
Device type: CPU (LE)
Device version: OpenCL 1.2 AMD-APP (923.1)
Driver version: 2.0 (sse2)
Global Memory: 3846 MB
Global Memory Cache: 32 KB
Local Memory: 32 KB (Global)
Max clock (MHz) : 2401
Max Work Group Size: 1024
Parallel compute cores: 2
..and now it fails on my laptop too :-/
magnum@...ge:~/src/john/src [1.7.9-jumbo-6-fixes]$ ../run/john -plat=1
-t -fo:bf-opencl
OpenCL platform 1: AMD Accelerated Parallel Processing, 1 device(s).
Using device 0: Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
****Please see 'opencl_bf_std.h' for device specific optimizations****
Benchmarking: OpenBSD Blowfish (x32) [OpenCL]... FAILED (get_hash[0](0))
This might be a bug in AMD APP.
