--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > We're waiting for Simon's patch at this point. For how long? > *** This bug has been marked as a duplicate of bug 80556 *** I doubt it since I am using ../work/configure --prefix=/opt/gcc/gcc8w --enable-languages=c,c++,fortran,objc,obj-c++,ada,lto --with-gmp=/opt/mp-new --with-system-zlib --with-isl=/opt/mp-new --enable-lto --enable-plugin --with-arch=corei7 --with-cpu=corei7 --with-stage1-ldflags=-static-libstdc++ --with-boot-ldflags=-static-libstdc++ which is supposed to be a work around pr80556.
