 * This tests is only valid for ix86 platforms, on others it's a no-op.
 * Some tests cannot be checked with ok(), for example the dtors. We simply
 * call them to ensure we don't crash ;-)
 *
 * If we build this test with VC++ in debug mode, we will fail in _chkstk()
 * or at program exit malloc() checking if these methods haven't been
 * implemented correctly (they have).
 *
 * Tested with a range of native msvcrt's from v4 -> v7.
