--- Comment #2 from David Faust <david.faust at oracle dot com> ---
Thanks, looks like something is going wrong with the CTF struct size
calculation.
.long 0x1a000005 # ctt_info
.long 0x1 # ctt_size or ctt_type
ctt_size here should be 0xffffffff as marker that the struct is too large to
use the regular type encoding and should switch to large struct encoding. The
rest of the failures are knock-on effects of that in the member bit offsets.
