The second position has no legal moves, so it's a stalemate with no possible PV. I don't know why the ce would be 1, however. In the third position, black is already mated, so has no legal moves. I'm looking through the source (I assume you're using Crafty compiled with the EPD support) to try and figure out why the first position isn't being analyzed properly (I get the same output as you did on my machine).
