Subject: Separate bitmaps report

Hi,

I am debugging 4 bitmaps for raw-md5-opencl. It works on my laptop but
caused memory corruption on bull. The report is as follows:

[19:53:18 myrice] run $ rm john.pot -f ; ./john -fo=raw-md5-opencl
-wo=md5.dic md5.hash -pla=0
OpenCL platform 0: NVIDIA CUDA, 1 device(s).
Using device 0: GeForce GTX 570
Local work size (LWS) 128, Global work size (GWS) 65536
Loaded 1 password hash (Raw MD5 [OpenCL])
end self test
*** glibc detected *** ./john: malloc(): memory corruption:
0x0000000009b27e20 ***

It happened either at the end of run or stuck at copying bitmaps from
CPU to GPU. Even I only changed previous defined cl_uint* bitmaps; to
cl_uint* bitmaps[1]; and changed every correspond place, the error
still exists. This code is in attachment.

I don't very understand this. Maybe I misuse array pointer in my code?

Thanks
myrice
