what's inside TELL_GNUGO() / ASK_GNUGO() ?

If you are using stdio, are you aware of buffering issues ?

if you are using unix, truss [solaris] / strace [linux] is a useful way of 
diagnosing
these sorts of things.

If your program is spawning gnugo, then

 truss -f your_program

will report system calls in your program and all sub-processes. You
should be able to tell whether your command is being delivered to
gnugo, and whether it is sending a reply which you are not receiving.

Otherwise you can use  truss -p <pid1> <pid2> to attach to running
processes.
