More XBoard bugs. How is f5g6 illegal move? Look at this game:

No legal chess fen found... no idea if this a trolling attempt?
(and moreover it has nothing to do with xboard/winboard, but polyglot refusing moves from your 'fen' as Black.)
This must be pre-xmas insanity.
Despite the illegal fen with 39 white pawns (seven of them on rank 1) no problem for winboard with uci2wb.
=> time control 0:01+0.1
