Unfortunately not.  The original code (before I lifted out the
functionality) sometimes had GFC_DEP_ERROR at the end of the
function, which was then removed by

  return fin_dep == GFC_DEP_OVERLAP;

That is very strange, there is an assert just a few lines before, that
fin_dep != GFC_DEP_ERROR.

This is not the only return statement.

For example, look at

@@ -2215,7 +2268,7 @@ gfc_dep_resolver (gfc_ref *lref, gfc_ref *rref, gf
          /* Exactly matching and forward overlapping ranges don't cause a
             dependency.  */
          if (fin_dep < GFC_DEP_BACKWARD)
-           return 0;
+           return fin_dep;

A GFC_DEP_ERROR could 'escape' here.

I didn't change the logic (at least not intentionally), I just made
it more visible.
