More on IVB first. Using 32 x 16 x 4 = 2048 looks to be too small to reproduce.
On the other hand 32 x 32 x 4 = 4096 looks to give 100% probability. The latter
has the buffer end at the page boundary suggesting that buffer overrun due to
alignment plays some role afterall (perhaps just something more complex than
discussed before).</pre>
