--- Comment #5 from Kimmo Kinnunen <kkinnunen at apple.com> ---
So the test jetsams because depth or stencil buffers are being allocated and they consume too much memory.
The buffers are freed eventually, but not during the test resize iteration.
The logic is:
  for (int i=0;i<10000;++i)
    resize()

The buffers do not seem to leak permanently, temporarily.

Maybe the buffers are retained in the command buffer, and we are clearing too many buffers without waiting for the previous buffer clears to complete.
