            PR fortran/120843

    gcc/fortran/ChangeLog:

            * resolve.cc (resolve_operator): Report inconsistent coranks
            only when not referencing this_image.
            (gfc_op_rank_conformable): Treat coranks as inconformable only
            when a coindex other then implicit this_image is used.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/coarray/coindexed_6.f90: New test.
