[H.G.Muller]

Indeed, this is a known WinBoard 4.8 bug. In that version I completely rewrote the move generator, but I forgot to put the Palace and River restrictions on Ferz, Wazir and Elephant when the variant is Xiangqi. Most annoying aspect is that it interferes with mate detection. It was subsequently fixed, but version 4.9 was only officially released as XBoard.

You can use the development version at http://hgm.nubati.net/WinBoard-AA.zip to get rid of this problem.
