When I did this, the size of the .ps file increased, but I'm still getting
an empty graph... Can anyone compile the following simple program with
GHC-5.02(.1) under a Windows platform and check how the heap profile looks
like?

main = print (f 25 + g 25)
f n  = nfib n
g n  = nfib (n `div` 2)
nfib n = if n < 2 then 1 else nfib (n-1) + nfib (n-2)
