I have a follow up test for pointers to arrays which is even more 
convoluted :-)

Right, test used 64 - but it could use any pointer size N, as the test 
doesn't really interop with any native library (in which case size would 
be an issue). This is merely creating a layout such and such, and verify 
that certain properties hold.
