Another would be having a platform where unaligned access isn't tolerated. It would be nice to have a big-endian platform, too, but I'm not sure if arm is a good fit there (my impression is that it can be run in either mode?). On the other hand, I think Ævar does periodically run on the gcc build machines, which includes examples of each (including aarch64). And this particular bug was found pretty quickly (within a week of it hitting next, and only a day after hitting master). So while it might be nice to have more immediate CI feedback, it does seem like the old "if the platform matters, somebody will try it and report the problem" strategy still works, too. -Peff
