    PR32560 stack-buffer-overflow at objdump disassemble_bytes

    There's always someone pushing the boundaries.

            PR 32560
            * objdump.c (MAX_INSN_WIDTH): Define.
            (insn_width): Make it an unsigned long.
            (disassemble_bytes): Use MAX_INSN_WIDTH to size buffer.
            (main <OPTION_INSN_WIDTH>): Restrict size of insn_width.
