This is a misconception, as jer already pointed out. Instead:
-Werror has forced you to take notice of problems that could have
resulted in data loss in ZFS ...
But in general it doesn't say when or how the problems became acute. Assuming
that the warning isn't bogus, it could have been the code relying on
undefined behavior, and the compiler changing the semantics of such behavior,
and introducing an accompanying warning at the same time.
