--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is ipa-icf going interesting. We mark c and d as clones of b. When we go
and do inlining, we fix up that a is no longer addressable because the check
for UBSAN_NULL is removed already.
So the real issue is after UBSAN_NULL is removed, there is no redoing
addressability of a.
