Is SPARC an architecture that would run into this problem? I think
there was a thread a few days ago about this...

What architectures are affected by this? I think I read somewhere
that ARM requires aligned accesses, too, right?

I wonder if it makes sense to emulate SPARC/ARM/... with QEMU on TravisCI [1].
Is this what you had in mind with "emulate" or do you see a better way?
If we compile and test in this environment - we should be able to catch
those bugs, right?
