This patch seems to have changed the behaviour of
display_debug_ranges(), such that the range start and end values it
prints no longer include the base address. The relevant lines from the
patch are:

-             printf ("    %8.8lx %8.8lx %8.8lx",
-                     offset, begin + base_address, end + base_address);

+             print_dwarf_vma (begin, pointer_size);
+             print_dwarf_vma (end, pointer_size);

Thanks,
Jay.
