Subject: [Bug gdb/29518] GDB doesn't handle DW_FORM_ref_addr DIE references correctly with .debug_types sections

--- Comment #2 from Greg Clayton <clayborg at gmail dot com> ---
Another way to fix this would be to artificially increase the "sect_offset" of
any type units from .debug_types that are added to the
"dwarf2_per_bfd::all_comp_units" to start at sizeof(.debug_info) + .debug_types
offset. If there are multiple .debug_types sections, then you would need to
increase any subsequent ones by the previous sizes. Since type units can only
have CU relative references and there is nothing that can reference anything
inside of the type unit from outside the type unit, it would most likely be
harmless. This would allow the "dwarf2_per_bfd::all_comp_units" to stay sorted
as things are added.
