--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
The IL after unswitching looks OK, but we assume that when &dso->i is NULL
then dso == NULL and when &dso->i is not NULL then dso also isn't.
I think this is a ranger bug that has been fixed on trunk
but eventually not yet backported, thus we have a duplicate somewhere.
Bisection will tell.
