OpenCL on Geforce 840M gives "field may not be qualified with an address space"

Hi

I have an OpenCL kernel which has been compiling and running fine on both Intel and AMD platforms, but is failing on NVidia. The problematic code is…

typedef struct This_s{
__private short _window[49];

giving

:2:20: error: field may not be qualified with an address space
__private short _window[49];

Any ideas?

Thanks
Barney

and how do you use window?
could you give an example of where it appears in your code?
