--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So from the information in the bug report, not setting -O2 in CFLAGS works.
This means `gcc version 3.4.2` is miscompiling GCC 4.3.1.
Since both of these versions of GCC is over 16 years old now there is not much
we can do. So closing as invalid.
