Description
Crash/assert hit in DXILForwardHandleAccesses pass on local resource array that was copied from a global multi-dimensional global array and passed into a local function.

}
[numthreads(4,1,1)]
void main(uint GI : SV_GroupIndex) {
for (int i = 0; i < 4; i++) {
Out[i] = foo(In[i], i);
}
}
