--- Comment #7 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Hmm, I configured with: ../configure --host=x86_64-pc-linux-gnu --target=powerpc-e500v2-linux-gnuspe --build=x86_64-pc-linux-gnu --prefix=/usr --bindir=/usr/x86_64-pc-linux-gnu/powerpc-e500v2-linux-gnuspe/gcc-bin/8.0.0-alpha20170702 --includedir=/usr/lib/gcc/powerpc-e500v2-linux-gnuspe/8.0.0-alpha20170702/include --datadir=/usr/share/gcc-data/powerpc-e500v2-linux-gnuspe/8.0.0-alpha20170702 --mandir=/usr/share/gcc-data/powerpc-e500v2-linux-gnuspe/8.0.0-alpha20170702/man --infodir=/usr/share/gcc-data/powerpc-e500v2-linux-gnuspe/8.0.0-alpha20170702/info --with-gxx-include-dir=/usr/lib/gcc/powerpc-e500v2-linux-gnuspe/8.0.0-alpha20170702/include/g++-v8 --with-python-dir=/share/gcc-data/powerpc-e500v2-linux-gnuspe/8.0.0-alpha20170702/python --enable-languages=c,c++ --enable-obsolete --enable-secureplt --disable-werror --with-system-zlib --disable-nls --enable-checking=yes --disable-esp --enable-libstdcxx-time --enable-poison-system-directories --with-sysroot=/usr/powerpc-e500v2-linux-gnuspe --disable-bootstrap --enable-__cxa_atexit --enable-clocale=gnu --disable-multilib --disable-altivec --disable-fixed-point --enable-e500-double --enable-targets=all --disable-libgcj --enable-libgomp --disable-libmudflap --disable-libssp --disable-libcilkrts --disable-libmpx --disable-vtable-verify --disable-libvtv --disable-libquadmath --enable-lto --with-isl --disable-isl-version-check --enable-libsanitizer and it compiles just fine for me. The ICE at that specific backtrace was fixed in quite robust way. Are you sure you did not test unpatched tree?
