Hi,
I am not sure, but possibly this will duplicate some other bug.

Bootstrap miscompares on latest 4.6.0 sources:


$ ../gcc/configure i686-linux --with-arch=corei7 --with-cpu=corei7
--enable-clocale=gnu --with-system-zlib --enable-shared --with-demangler-in-ld
--enable-cloog-backend=isl --with-fpmath=sse --prefix=$PREFIX
--enable-languages=c,c++,fortran
$ make -j24
