Fortran does not call by reference, and the term aliasing isn't used by the standard. It calls by what's usually called value-return or copy-in/copy-out, according to the "storage association" rules in the standard. While it may be true that the rules aren't generally checked by compilers, Toolpack did it for pure Fortran77 in the 1980s, though I don't know how comprehensive it actually was.
