It would need some care in construction to ensure good mortar seals, but you need that even with a normal brick wall (think a wind blowing rain against the wall). With proper mortar treatment the only difference would be that some water could sit on top of the horizontal parts of the bricks, but that really shouldn't cause damage, even if it were to freeze.
