Hello Bernhard,

You are the second person to report this. The program seems to work well in 32-bit Linux (Volker Pittlik managed to compile it and reports promising early results; his binary will be added to the downloadable package from my web site later today), but clearly there are problems in 64-bit Linux.

Could you please try to comment out the line with #define USE_32BIT_ATTACKS near the top of bitboard.h and recompile everything (you have to do a "make clean" before recompiling, I think)? If this does not help, could you try running the program in gdb and inspect where the crash occurs?

Change in .h doesn't help.

running gdb gives:

Thanks! I don't understand why this happens, but I have posted about the problem in the programming sub-forum. I hope someone will be able to give us advice.

Hello all,

I actually advise Bryan, Jim and Dann to wait a little longer with the Windows binary. There are some compatibility issues I'm working to solve first; I plan to prepare an updated version of my source code later today.
