While playing around with gnuchess to see how well (or not) it 
dealt with stalemate, I found the following erroneous claim of a checkmate!

White King on b4, Knight on e2, Bishop on h7 and Rook on h2
Black King on b2

White moves Nc3, and the program claims Opponent mates!
My reading of the set up is that a1 or c1 is possible.

Solutions? Explanations?
