Either you or I has missed something here.  I'm using gnuchess 4.0pl75 on 
Linux, with a bugfix posted quite a while back (January, I think) by 
Kong Sian.  I t;hink it's in the FAQ, but here's a patch:

$ diff -u gnuchess-4.0.75.orig/src/search.c gnuchess-4.0.75/src/search.c

Had you already applied this patch, and still had trouble?  The crashes I 
had (when gnuchess tried to think for itself) disappeared with this.

Hope this helps,

Nikhil.
