... and both revisions should be in the 4.0 branch (taken from r291814)

I was looking forward to this warning to help iron out alignment issues at compile-time instead of runtime (our ARM CPUs don't like unaligned access). @royger, can you expand a little on what you mean by

> For once, it doesn't really check whether the access is actually unaligned or no

? Isn't that exactly what it does? Or do you mean in relation to whether the target allows unaligned access or not?
