The problem was that the cuda driver api takes kernel arguments as an array of pointers to the argument values. This was the go-pointer-to-go-pointer issue. To make matters more complicated, the pointer check is conservative and treats a pointer into a struct as passing the entire struct. Finally, non-pointer values stored inside an unsafe.Pointer occasionally cause a "fatal error: bad pointer in write barrier".
Fix is rather ugly:
