Comment 37 for bug 1042388

I finally got round to looking into why the test case from comment #27 worked on x86-64 guests and i386-guest-on-i386-host but not on arm-on-x86-64. This turns out to be a wrong structure definition which meant we weren't handling the 32-bit-guest-on-64-bit-host combinations correctly. I've sent a patch:

I think this should tie up the last loose end in this bug report so once it gets into master we can close it.
