rrdtool -graph using excessive memory

[sejtam]

I just realized that for some graphs, 'rrdtool -graph' takes excessive amounts of memory (300MB).

$ rrdtool -version
RRDtool 1.2.15 Copyright 1997-2006 by Tobias Oetiker <tobi@oetiker.ch>

Has anyone else experienced this?

Some more data:

The process(here at 200MB size still growing):

Is this a memory-leak?

Hi

I had the same problem with 1.2.15, running on Gentoo.
I've downgraded to 1.2.13
