--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> --- Not necessarily errorneous. In this particular case, we simply lack the ability to tell deja-gnu to expect this to pass at -O0 but expect it to fail at any higher level. We have consciously decided to cope with XPASSes (as opposed to coping with FAILs or duplicating the testcase).
