Re: Linux port of newer versions of TogaII
Seems to be 100% on the second non-book move. Or on move 2 if you take away the book. These latest tests were with 1.41SE, but I get same stuff with 1.45bc as well.

Re: Linux port of newer versions of TogaII
Thanks for the info,
You didn't specify if your computer is 32/64 bit. How many CPU's?
Unfortunately for the moment I cannot reproduce the problem on Linux. But it must definitely be a bug in the toga sources which must be squashed. I will try to think about what it can possibly be.
For the record, and if you have time, could you run polgyglot with a log file and post the exact UCI commands leading to the crash? Since as you say the crash occurs at ply 2 there should be only a few. Then I can try to run Toga under a memory debugger to see if that reproduces the problem.
Even the single threaded version of Toga 1.4.1SE is still substantially stronger than 1.3.4 accoding to the CCRL. So there is still a point in compiling the latest Toga's for the Mac.
Regards,
Michel

Re: Linux port of newer versions of TogaII
My system is 64-bit, 8 cpus. Number of threads used when compiling hasn't made a difference, compiling 32 bit or 64 bit doesn't make a difference either. I do have 3.1.2SE compiled for single thread which is very similar in strength 1.4.1SE.
What might be interesting would be to see if the crash is reproducible on a BSD system.
Polyglot log does not tell too much:

Re: Linux port of newer versions of TogaII
Ok I really can't reproduce this on Linux. Neither valgrind, libefence or gdb notices anything
suspicious when running a 2 thread binary.
These are the commands polyglot sends
If you have time can you compile with -g and produce a backtrace with gdb (don't forget to NOT strip (LDFLAGS+=-s) the binary). Here is what I get
As you can nothing special. In your case there should be a segmentation fault and then
you can do "bt" to get a stack trace.
Alternatively I think I have some BSD livecd's lying around. I can play with that but this will
have to wait a bit until I find some free time.

Michel

you can do "bt" to get a stack trace.
Alternatively I think I have some BSD livecd's lying around. I can play with that but this will
have to wait a bit until I find some free time.

Re: Linux port of newer versions of TogaII
It seems gdb is thoroughly confused. Presumably the segfault does not occur at the actual
memory access error
(this very often happens in my experience). To debug this one should link with libefence
http://perens.com/works/software/ElectricFence/
(LDFLAGS+=-lefence).
If you then run gdb (after compiling with -g) you usually get the actual line where the error occurs.
This being said I am starting to be somewhat pessimistic....

Michel

Re: Linux port of newer versions of TogaII
It seems the source of libefence needs a small modification to work on MACOSX.
This is supposedly a modified source.
