Research direction

Start in source/compiler/qsc_passes/src/replace_qubit_allocation.rs at generate_qubit_alloc_stmts, where the panic occurs. Reproduce it by compiling the shown Q# operation through the eval harness and qubit-allocation pass; done means use _ = Qubit(); no longer panics and compilation proceeds successfully.
