    PR24898, An out-of-bounds read occured in display_data

    Given 32-bit pointers and a 64-bit bfd_size_type, it is relatively
    easy to construct a value of augmentation_data_len (eg. 0x100000000)
    that won't fail pointer checks but will print without bounds.

        PR 24898
        * dwarf.c (display_debug_frames): Use the read_cie check and error
        for augmentation data length.
