For future reference: In situations like that, it might be useful to 
compile both C++ and D sources to LLVM IR (`-emit-llvm -S` for Clang), 
and then manually assemble them using `llc`.

Any difference in behaviour that remains must then be visible from the 
IR, rather than some potentially different codegen settings, etc.
