when GCC is configured with

--prefix=/usr/5.0.0 --enable-clocale=gnu --with-system-zlib --enable-shared
--with-demangler-in-ld --with-build-config=bootstrap-lto --disable-werror
--with-fpmath=sse --enable-languages=c,c++,fortran,java,lto,objc

and built with "make -j8 profiledbootstrap". r219906 is OK.
