Are you seeing them outside of src/ptserver or src/tests? The ptserver
ones are known and really annoying to fix, but both should indeed be
getting -fno-strict-aliasing.

Outside of there, please give some examples, because at least I'm not
aware of them. And they probably don't happen on at least Linux, since
Linux builds are done with --enable-checking fairly often; I'd think we
would have noticed.
