sure. not the pi itself but other similar devices which have that processor clas?

  Sort of? You'd also need a way of guaranteeing total store order semantics for memory otherwise you may get random errors. I guess restricting the app to a single core might reduce that error frequency a bit

    > I guess restricting the app to a single core might reduce that error frequency a bit Shouldn't it eliminate it entirely? I'm pretty sure ARM guarantees sequential consistency on a single core, so if the app is limited to a single CPU (e.g. using taskset), there should be no issue. The real problem is, performance will be degraded.

        I'm skeptical, but optimistic. qemu user emulation with TCG is also a JIT compiler, is pretty decent, and doesn't have the "needs to be limited to a single core" when ran outside macos hardware, though it certainly has a lot of room for optimizations. I'm waiting for some benchmarks comparing the two.
