--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You must have CXXFLAGS set to be "-march=3Dnative -O3 ". If so you should be
using --disable-werror too.

Can you attach the preprocessed source for charset.cc ?
Also Please provide the output with -v while compiling charset.cc since
-march=3Dnative will expand to something different depending on what machin=
e you
run gcc on.=
