I've moved my target machine setup to immediately after creating

<div>You might need to set your TargetOptions before calling
selectTarget. E.g.</div>

<div>If those are still failing, it would be interesting to get
the data layout string that you are getting from the
ExecutionEngine instance and compare it to what you are
expecting.</div>

Is that enough to create an appropriate DataLayout for the
