Hello there,
I've been having a lot of trouble with Gnuchess-4.0.pl74.  I run Xboard as
an interface to Gnuchessx and it crashes when it 's played for about 30 
moves even though It played very well.  I then posted a message here to 
search for answers.  Tim Mann suggested that because of the gnuchess.hash
file, but there was no such file!. Then I got a suggestion
from Kongsian(one of gnuchess programmers). He said that there is a bug in 
the internal transposition table(the -Dttblsz compile option). So I got the
latest update of GNuchess-4.0.pl74 and compiled it with with -Dttblsz=0,
but it would not compile the search.c file even though other files were
OK!Then I switched to the option that turned off the transposition file by
using -initString "new\\n...hash\\n" command line option.  The surprising thing
is that gnuchessx will play and never crashes(0%) on games that are less than
50 moves!!!  However, for games that are more than 50 moves, it will 
ALWAYS(100%) crashes!!! So I'm stuck right now.

Anyone who has any idea what the problem might be, Please reply.
Any response is greatly appreciated.  Thanks.

P.S.: By the way, if anyone knows how to start up gnuchessx using WinBoard,
please tell me. I know that there are help files(I read Winboard.hlp already). 
However, it seems that I can't figure out the right command-line 
otions to do it(I'm using Windows NT Workstation).I got error messages like
'permission denied' or 'cannot find gnuchessx'
