Prevent Stockfish from exiting if DTZ table is not present During TB initialisation, Stockfish checks for the presence of WDL tables but not for the presence of DTZ tables. When attempting to probe a DTZ table, it is therefore possible that the table is not present. In that case, Stockfish should neither exit nor report an error. To verify the bug: $ ./stockfish setoption name SyzygyTable value <path_to_WDL_dir> position fen 8/8/4r3/4k3/8/1K2P3/3P4/6R1 w - - go infinite Could not mmap() /opt/tb/regular/KRPPvKR.rtbz $ (On my system, the WDL tables are in one directory and the DTZ tables in another. If they are in the same directory, it will be difficult to trigger the bug.) The fix is trivial: check the file descriptor/handle after opening the file. No functional change.
