I've been getting this same CUDA error at random for a few months. I've already reported my issue. My specific problem sometimes only shows up after working on a scene for a day or more then I add a single prop and all hell breaks loose and all I get is render crashes from that prop. Sometimes changing the mats on the prop will fix it and sometimes it does not. I've gotten the crash with my free super shader and other times it renders just fine. It's very hard to pin down what is happening.
