Here's a game with gnuchess-4.0 that looks pretty suspicous:

There were many moves better than b6e3 available to gnuchess that
would have prevented the mate, at least for awhile. In fact, I was
worried about losing this one as white. You can see that the score
change is pretty radical.

gnuchess had 1:20 (as shown by xboard) left on its clock when it
committed the blunder in a 5 minute game. Unfortunately, I expect
random mode was on and the transposition table enabled.

BTW, I just realized that gnuchess is generating these files. It's
leaving them sitting in the executable directory under names like
CLp45.Jun11-145947B. Is it supposed to this?

I have applied no patches since the 4.0 release. The game was played
on a SUN 4/110 under xboard. I don't remember executing any commands
other than making moves. I believe my flag fell while I was sitting
with my jaw in my lap trying to figure out why his last move was so
bad--perhaps this is a feature? :-)
