    PR29171, invalid read causing SIGSEGV

    The fix here is to pass "section" down to read_and_display_attr_value.
    The test in read_and_display_attr_value is a little bit of hardening.

            PR 29171
            * dwarf.c (display_debug_macro, display_debug_names): Pass section
            to read_and_display_attr_value2.
            (read_and_display_attr_value): Don't attempt to check for .dwo
            section name when section is NULL.
