--- Comment #14 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- Results with the patch in comment 11 at https://gcc.gnu.org/ml/gcc-testresults/2015-03/msg02484.html Note that the patch in comment 6 also fixes this PR. It is probably the best short term solution. Could it be committed for 5.1?
