--- Comment #5 from janus at gcc dot gnu.org --- (In reply to Marek Polacek from comment #4) > The preprocessed source doesn't ICE for me neither. Huh, I guess then the problem is with me not doing a full bootstrap. I'm configuring with: --program-suffix=-7 --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu --with-arch=haswell --prefix=/usr --libdir=/usr/lib --libexecdir=/usr/lib --enable-languages=c,c++,fortran --disable-bootstrap --disable-multilib Will check if enabling bootstrap solves the problem.
