[Click] Click problem

[Capisani Luca]

Hello,
        I'm Capisani Luca, I'm graduating in Computer Science in 
university of Mantua (www.unimn.it), Italy.
For my thesis, I choosed the click nat-pt translator. After that, with 
the aid of J.M. Baptiste, I installed the click with nat-pt package in 
a linux 9.2 2.4.22 kernel.
I configured the translator, and finally I encountred some problems 
regarding click.
In particular, the nat-pt translator worked, but irregularly during the 
translation, the click program exit with error SEGMENTATION FAULT (some 
times SEGMENTATION FAULT (CORE DUMPED))
This error appears sometimes also if I use the IPPrint click element, 
and it seems to be more frequent if I use the click print elements.
 
What should I do?
 
(Excuse me for my bad english)
THANK YOU...
CAPISANI LUCA.
