--- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
We do very basic ODR check in ipa-devirt, perhaps we can extend it to handle
this case, too.

But as a fallback we should probably also stop ICEing when things progress to
actual fold (I saw ICEs like this before but they all tracked down to bugs in
devirtualization logic, this is first one that really come from misformed
source code).
