--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
_ZTI7Derived.0_1 = &_ZTI7Derived;
_3 = MEM[(const struct type_info *)_ZTI7Derived.0_1]._vptr.type_info;
_4 = _3 + 18446744073709551608;
_5 = *_4;
Is being optimized to be 0 for some reason.
Looks like _ZTVN10__cxxabiv120__si_class_type_infoE (vtable for
__cxxabiv1::__si_class_type_info) is not being recorded correctly inside GCC.
