--- Comment #1 from ktkachov at gcc dot gnu.org --- I tried a bootstrap of the GCC 5.3.0 release as taken from one of the mirrors in: https://gcc.gnu.org/mirrors.html This was done on an ARMv8-A machine inside an aarch32 chroot with binutils 2.24 and glibc 2.19. The configure command was: --target=arm-none-linux-gnueabihf --build=arm-none-linux-gnueabihf --host=arm-none-linux-gnueabihf --with-arch=armv7-a --with-float=hard --with-mode=thumb --with-fpu=neon --enable-languages=c,c++ --disable-multilib --with-system-zlib --disable-libstdcxx-pch --enable-plugin The bootstrap succeeded without problems. I'll try again with passing BOOT_CFLAGS="-O2 -g0" to the bootstrap
