i updated to the exact same driver version and tested on a GTX295 and
all OpenCL 1.0 tests are green (HelloJOCL works too..).

could be a driver issue. As i mentioned in my previous mail the segfault
happened as the exception string for a failed build was assembled
(asking the compiler for the build log). You could run into a cornercase
where the driver decides to invalidate the program when the build fails
or something like that (which would not be spec conform of course). NV
OpenCL drivers are known to be not up2date, I don't think i can do much
to resolve the issue.

You could try to install the AMD or Intel sdk and run it on the CPU if
you like.

best regards,
michael
