Stockfish 2.3.1 update available

[Modern Times]

OK, posiiton 9 crashes with 2.3.1 for me too

But this bug is new to 2.3.1.

Position 9 is fine with the compile Marco sent me directly a few days ago, and which contained just the previous FRC bug fix and nothing more.

I am not able to reproduce the issue. Coul you please test from command line with the following:

Code: Select all

$ ./stockfish 
Stockfish 2.3.1 by Tord Romstad, Marco Costalba and Joona Kiiski
position fen qnnbbrkr/pppppppp/8/8/8/8/PPPPPPPP/QNNBBRKR w HFhf - 0 0
go infinite

It is working for me.

[Modern Times]

That works fine

[mcostalba]

That works fine

Please try also this one that is the correct sequence:

Code: Select all

$ ./stockfish 
Stockfish 2.3.1 by Tord Romstad, Marco Costalba and Joona Kiiski
setoption name uci_chess960 value true
position fen qnnbbrkr/pppppppp/8/8/8/8/PPPPPPPP/QNNBBRKR w HFhf - 0 0 
go infinite

The second one is what I did, and that worked. The first one crashes.

Did you edit your posts ? Both of those crash when I re-do them. Or perhaps I tried 2.3 before. Anyway - both of what you have above crash.

Yes, you really need

Code: Select all

setoption name uci_chess960 value true

Could you please check the "Use Debug Log" option then post io_log.txt file content after it crashed in your GUI?

[Modern Times]

so it crashes at command line as well as the GUI

After the GUI crash, the log is
>> isready
<< readyok
>> ucinewgame
>> isready
<< readyok
>> setoption name UCI_Chess960 value true
>> setoption name UCI_AnalyseMode value true
>> position fen qnnbbrkr/pppppppp/8/8/8/8/PPPPPPPP/QNNBBRKR w HFhf -

I'm seeing it crash with stockfish-231-64-ja.exe, however, with my local compile it doesn't crash. I wonder if the pgo is hitting a bug?

Yes I confirm I can reproduce the crash with Jim's 64bit binaries, both popcount and not popcount, on my Windows 7. The 32bit one seems to work instead. Moreover my local 64 bit (MSVC) compile doesn't shows this behaviour.

Jim, does it crashes for you? Try this:

Code: Select all

$ ./stockfish
Stockfish 2.3.1 by Tord Romstad, Marco Costalba and Joona Kiiski
setoption name uci_chess960 value true
position fen qnnbbrkr/pppppppp/8/8/8/8/PPPPPPPP/QNNBBRKR w HFhf - 0 0
go infinite
