I'm sure they'll crack over enough freeze-thaw cycles, just like anything, but I wouldn't worry about it too much. Most pots are an inch or so of good solid stone and don't have any undercuts, so the ice layer on top can get pushed upwards by the water below freezing & expanding, instead of putting all that stress into the pot walls.

So catastrophic failure seems unlikely. The freeze/thaw cycles will just keep expanding the existing cracks in the wall until some part of the pot wall finally gives. More likely to be next decade than next year though.
