Still doing the same thing. Looks like it is still hanging in TB search.Jeremy Bernstein wrote:OK, sorry for all the builds. Here's a version which does what I just explained above.

How many threads are you using? I can't reproduce using a single core -- it iterates to 100 and then waits for a stop (when go infinite is issued). In this case, it should be possible to break early from the search, but that's a different issue.Uly wrote:I had Stockfish crashing in this position:
Sorry that fixed the problem. I was using the wrong version. Using 12 threads.Jeremy Bernstein wrote:How many threads are you using?

I also tried running Uly's problem and here's what I got.keoki010 wrote:Sorry that fixed the problem. I was using the wrong version.

Is there a big difference between Nalimov and Griviota hits. The last build I tried seemed to start getting less hits for stockfish then for R4. I will try the last build and let you know.Jeremy Bernstein wrote:OK, please try this build. I found (thanks to Jouni Uski) a somewhat serious bug in the TB code, where capture moves from a 6-piece position could have triggered a premature search stop, if a tablebase hit resulted.
Uly's position gives me a mate in 14 for black (after Nxf2) using 2 threads. Any other move is even worse for white.
This build seems to not get as deep as the last build depth wise but seems to get better results on analysis. I'll play with it a little more tomorrow. I have to get off my computer now.Jeremy Bernstein wrote:OK, please try this build.
