I guess I'll see... Probably insn_get_seg_base() itself can verify if there are segment override prefixes in the struct insn. If yes, use them except for specific cases such as CS. On an unrelated note, I still have the problem of using DS vs ES for string instructions. Perhaps instead of a use_default_seg flag, a string_instruction flag that indicates how to determine the default segment.
