--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
It is a non-trivial transformation ;) First 'foo' has to be promoted to a
constant. It's not written to - but it has its address taken, so to prove
that is non-trivial (and not done IIRC). Then we have to apply IPA-CP.
I guess it's IPA references fault in some way.
Btw, on trunk we inline the function but fail to constant fold from the
initializer.
