Crafty 23.0(JA) bug

Post by Guenther »

In the game below Crafty claimed a non existent mate in a drawish
position near the 50 moves rule limit in a 6 piece endgame after
the internal board got corrupted.
The game was played with PO and with single CPU on a Q8200
with all 4men + RX vs.R and QX vs. Q 5men TBS.

Edit: Online 6men TBS say it is still a mate in 32 for Black, but I doubt
it would have been found by Rybka 2.32 ... I am also unsure and did
not check if it would have hit the 50 moves barrier with correct play
from here on.

Re: Crafty 23.0(JA) bug

Post by bob »

Was the analysis from repeating the test or from the log.nnn file? If it is repeatable, I will try to debug it and see if it is a crafty issue or a compiler issue. I've not seen any such losses in any of the tens of millions of games we played before releasing 23.0...

The last output was directly from Craftys game log for this game.

I was afraid of that. That means it may well be very difficult to reproduce it. Or impossible if it is really a compiler issue. We have played over 40,000,000 games since 23.0 was released. Any crash is instantly flagged, and we are not getting them, except for those occasions where a change doesn't quite work as planned and produces a bad subscript or something similar. And we fix those instantly since they wreck the testing.
