--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
Pre rich locations, it should have looked like

    #     [name]:[locus]:
    #
    #       some code
    #              1
    #     [name]:[locus2]:
    #
    #       some other code
    #         2
    #     Error: Some error at (1) and (2)
    # or
    #     [name]:[locus]:
    #
    #       some code and some more code
    #              1       2
    #     Error: Some error at (1) and (2)
