Thanks.

The line at zero is how I would have done it on previous versions of rrd.

It's not totally clear from the manual but I interpreted the idea of 
changing STACK to an argument of AREA was so that you wouldn't have to make 
a special case for the first item in a stack.

If the behaviour is not supposed tobe be this way segfaulting rather that 
giving some kind of error message can't be good.

Cheers,
David
