--- Comment #8 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Do you see the regression, with r219973 in place, if you bootstrap with gcc > 4.9.2 rather than gcc 5.0svn? It also seems odd, if r219973 triggers this bug, > that you see it when bootstrapping with a gcc 5.0svn compiler built prior to > r219973. ??? Sorry,I don't understand what you are asking for: the ICE seems independent of the bootstrap compiler (assuming FX is using clang).
