--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> ---
One thing which might help to figure out which file is miscompiled at least.
So swap out some .o from before and after might help there.
The other thing is add -fdump-tree-all and see which file/function is changed
there. It might be a vectorization issue; add -fno-tree-vectorize to see if
something changes there.
