Hello, I am building GCC 9.1 in Ubuntu 16.04 (the host compiler is GCC 5.5.0). The GCC 9.1 source is the tarball released earlier this month after the release announcement. The build is done in a separate build directory with the following configure command: ../gcc-9/configure --program-suffix=-9 --enable-languages=c,c++ --with-gcc-major-version-only --enable-shared --enable-linker-build-id --without-included-gettext --enable-threads=posix --enable-nls --enable-bootstrap --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --with-default-libstdcxx-abi=new --enable-gnu-unique-object --disable-vtable-verify --enable-plugin --with-system-zlib --with-target-system-zlib=auto --enable-objc-gc=auto --enable-multiarch --disable-werror --with-arch-32=i686 --with-abi=m64 --with-multilib-list=m32,m64,mx32 --enable-multilib --with-tune=generic --enable-offload-targets=nvptx-none --without-cuda-driver --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu Afterwards, I issue the following command: make profiledbootstrap After 10 hours or so, and I think it is near the end of the build process, the build fails with the output given at the end of this e-mail. Files stage_current, stage_final, and stage_last have the same content `stagefeedback'. I found in the mailing list archive https://gcc.gnu.org/ml/gcc-help/2012-04/msg00093.html, but it has no solution. Could someone help me solve this problem, please? Thank you very much. /bin/bash ../libtool --tag CXX --mode=link /home/eus/buildzone/gcc-9-build/./gcc/xgcc -shared-libgcc -B/home/eus/buildzone/gcc-9-build/./gcc -nostdinc++
