This test has a lot of classes with large amounts of manually inserted padding in them, presumable to prevent various optimizations.  The test then creates lots of these objects on the stack.  On embedded targets, this was usually enough to overflow the stack.

I reduced the padding significantly.  I made the padding values prime to try and keep the evil optimizations at bay.
