Research direction

Start with the reproducible HLSL case at https://godbolt.org/z/n9h3oP9a and use the reported dxc version and host environment to reproduce the compiler error. Trace the incompatible cast diagnostic through the compiler, then verify that the same case no longer produces an internal compiler error and has an appropriate result.
