I'm not familiar with the stack-like functions mentioned, but that is indeed something it should NOT eliminate. In fact, the compiler should not eliminate 'dead stores'. That should be a warning (and emit the code) OR an error (do not emit a program). The compiler should inform the programmer so the PROGRAM can be made correct. Not so it's particular result can be faster.
