* Most structure members have bit offsets that can be expressed using a * short. Some don't. ctf_member_t is used for structs which cannot * contain any of these large offsets, whereas ctf_lmember_t is used in the * latter case. If ctt_size for a given struct is >= 8192 bytes, all members * will be stored as type ctf_lmember_t.
