Assigning vertex normal in Surface program to o.Normal brakes lighting?

I have encountered strange problem. If I get v.normal in vertex program and pass it to surface program and assign it to o.Normal - light is breaking, like there are incorrect normal. But I just take vertex normal, no manipulations. Am I doing something wrong?
