--- Comment #12 from Jan Kratochvil <jan.kratochvil at redhat dot com> --- That looks as a DWARF5 bug to me. DW_AT_str_offsets_base, DW_AT_addr_base and DW_AT_rnglists_base do not make any sense for a split unit. Split unit contains only one CompileUnit (and optionally one TypeUnit where only DW_AT_str_offsets_base would have some sense).
