Looking into this again, why not as shown below?  IMHO, this way the
code will be logically the same as it was before the patch, basically
why to process an extra statement ( *volatility_item = defel;) if we
have already decided to error.

 if (is_procedure)
    is_procedure_error =  true;
else if (*volatility_item)
  is_duplicate_error = true;
else
  *volatility_item = defel;
