Problem with GNUChess [as white] and Gothmog [as black]

[n o s p a m p l e a s e]

I failed to run the above match on winboard. The debug report is
appended below.

GNUChess and Gothmog runs with other programs as white or black without
any problem. When it comes to GNUChess [version 5.07] as white and
Gothmag as black, it lands up into the problem.

I am unable to resolve this problem. Any suggestions!
