Minor. Should be fixed in CVS now.

Weird. I guess it's the

  size == RLIM_INFINITY

test. What's RLIM_INFINITY on your system ? ( in /usr/include/sys/resource.h
presumably ).

In any case, I don't know whether it's a real problem. How does gp react to
the following:

  dive(n) = dive(n+1)
  dive(0)

??
