--- Comment #4 from William J. Schmidt <wschmidt at gcc dot gnu.org> 2012-04-14 00:07:11 UTC --- I've found that the cpu2006 failures are fixed by the patch in PR52976. I have to leave for an obligation tonight, but will investigate the remaining failures in these two issues tomorrow -- they all have the same symptom, so hopefully only one remaining problem.
