--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-04-03 09:07:46 UTC --- I successfully bootstrapped revision 186090 on powerpc-apple-darwin9. From http://gcc.gnu.org/ml/gcc-testresults/2012-04/msg00234.html it seems also fixed for powerpc64-unknown-linux-gnu. So this PR could probably closed as fixed.
