     Fortran: Fix ICE on invalid code

     This patch tests whether a symbol imported into an interface
     is already available in local scope.

             PR fortran/123375

     gcc/fortran/ChangeLog:

             * decl.cc (gfc_match_import): Check that imported entity within
             a interface is not from local scope.

     gcc/testsuite/ChangeLog:

             * gfortran.dg/import.f90: Run code testing for a warning that
             is now an error.
             * gfortran.dg/pr123375.f90: New test.
