--- Comment #1 from Markus Trippelsdorf <octoploid at yandex dot com> ---
The following is enough to reproduce the issue:

 % ../gcc/configure --with-tune=amdfam10 --enable-checking=release
--disable-werror --disable-multilib --enable-languages=c,c++
--with-build-config="bootstrap-lto bootstrap-O3"
 % make profiledbootstrap

Maybe it is another target problem?
