[Click] click nat-pt ping segmentation fault

[Ciprian Ocean]

Dear reader,

My name is Ciprian Ocean, I am a student at the Technical University
of Cluj-Napoca, Romania. I am working at my diploma thesis about
translation mechanisms. I am searching a sollution for translation on
OpenWRT. I hope that you'll help me to clarify some things about Click
or Click NAT-PT.

The thread describes exactly my problems with nat-pt on click. I
observed too that Print elements change the behavoiur of the nat-pt
router and I also get segmentation fault when no Print elements are
used but this varies. Somethimes ICMP tests can be done other times
they cannot. My network configuration is IPv4-translator-IPv6. The
graph configuration file for click is the nat-pt configuration
modified realized by Juan Luis Baptiste and Fabian Gonzalez.
Searching further i found that the nat-pt problem doesn't include ALG
in the configuration graph.

My question is if the translator elements addresstranslator,
protocoltranslator64 and protocoltranslator46 are the cause in
segmentation fualt or is there a queue problem or driver element
problem.  Was a patch developed?

Ciprian Ocean
