--- Comment #17 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
So this turned out to be disabled ODR based TBAA for this struct since on ARM
the builtin va_list type has same structure.
I fixed the fialure by adjusting the structure and next stage1 we can make ODR
TBAA to not give up in this case.
