--- Comment #20 from David Edelsohn <dje at gcc dot gnu.org> ---
This probably is related to PR 28586. The detail that the failure occurs when
exceptions are thrown within constructors was important.

MD_FALLBACK_FRAME_STATE_FOR has been implemented to 32 bit AIX but not 64 bit
AIX. That probably explains why this works in 32 bit mode but not 64 bit mode.
