fread: Success Segmentation fault /

What version of the product are you using? On what operating system? BT5R2, pyrit 0.4.0, NVIDIA 295 GTX, CUDA 5.5

I had 250 GTS was working well when i changed to 295 GTX i start to get segmentation fault, unfortunately i don't have old graphic card. pyrit benchmark and core_list show two of them. Can't find anything on internet.

a segmentation fault can be caused by all sorts of things going wrong, and your description isnt enough to tell what the problem is ....
