Excerpt from the generated DWARF debug info:

I see the issues to be the result of:
#1. The gen_ctf_sou_type function is processing
<3><6a>: Abbrev Number: 6 (DW_TAG_const_type)
as a member of the struct.
#2. The top-level DIE
<1><8e>: Abbrev Number: 1 (DW_TAG_pointer_type)
is being processed by ctf_do_die.
