broken OpenCL/OpenGL interopeability

on AMD CPU + nVidia GPU

just tryed my project on laptop with AMD+nVidia OpenCL.

first when both platforms are present (nVidia+AMD) it works only when i run throuth debugger. when i run normaly i got "Bus error" but that is maybe error in my code.

second my OpenCL/OpenGL interoperability in CPU mode work on my developer PC with phenom II 965 and radeon 5850. and it work even on ubuntu in virtualbox where it is software Mesa OpenGL hosted on MacBook.

but it fails on third laptop with nVidia GPU. i mean combination AMD OpenCL+ nVidia OpenGL. when both CL and GL is nVidia then it work. all my test was on Ubuntu.

I did not face any such issue on my laptop(CPU=Intel(R) Core(TM)2 Duo and GPU=GeForce 8400M GS)

I am able to run SimpleGL, NBody and URNGNoiseGL on CPU without any problem.

I am using ATIStream SDK 2.3.

SimpleGL and URNGNoiseGL works. but NBody segafault. it is not much big deal as i have in my application both path throuth host memory and CL/GL interoperability.
