    Fix seg-faults when running readelf on fuzzed binaries.

        PR binutils/20440
        * dwarf.c (display_debug_lines_decoded): Add checks for running
        off the end of the section when populating the directory table and
        file table.
        (frame_display_row): Set max_regs equal to ncols.
        (load_specific_debug_section): If the section is compressed, but
        it is not big enough to hold a compression header then warn and
        return 0.
