rrdgraph segmentation fault when using VDEFs

rrdtool graph /var/www/temps/data/day.png \

Segmentation fault. That's it. If I use the old version of GPRINT, which is something like GPRINT:Inside:MAX:"Max\: %6.2lf°C\t" etc. the script runs fine. RRDtool version 1.2.23 compiled from sources. Platform is Linksys NSLU2 with debian GNU/Linux with kernel 2.6.22. I do have, however, some problems regarding the pngs rrdtool creates. With the script above, creating one png takes 30 minutes and still in the graph at "max" is a VERY large number, at "min" same but negative, at "average" -inf and at "latest" 0 (the script above doesn't include but the LAST lines for clarity).

hmmm this may be a compiler related issue, check the mailinglist archives.
