This is OK. The avr GCC community needs to know this so they can decide what to
do. Unfortunately as much as we would like all targets to upgrade in lockstep,
it doesn't happen. We would need a more aggressive testing program to know this
as early as possible and attempt to fix an issue. And we could still end up in
this situation.
