--- Comment #37 from David Edelsohn <dje at gcc dot gnu.org> ---
Jakub, the -fcompare-debug failure is not new.  The root cause has been
analyzed before. AIX specifically does not want to push unnecessary stack
frames for code that is not compiled with debugging solely for matching code
generation.
