```hlsl
struct S {
float a;
};
StructuredBuffer<bool> Cond : register(t0);
StructuredBuffer<S> TrueVal : register(t1);
StructuredBuffer<S> FalseVal : register(t2);
RWStructuredBuffer<S> Out : register(u3);
[numthreads(1,1,1)]
void main() {
Out[0] = select(Cond[0], TrueVal[0], FalseVal[0]);
}
```
This code, when compiled, produces this error:
```
# .---command stderr------------
