--- Comment #27 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-01-08 13:00:10 UTC --- Note that reapplying r181405 with the Richard Sandiford's patch at http://gcc.gnu.org/ml/gcc-patches/2011-11/msg02004.html fixes the failures on powerpc-apple-darwin9 without visible side effect on x86_64-apple-darwin10.
