  Message : Use local variable isntead of function parameter The parse_size() wrapper around scan_scaled(3) writes its intermediate result to the function argument which is always passed as literal zero. This seems odd, the function parameter has no meaning but merely serves as storage, so let's use a proper function scoped variable instead. OK pd
