Segmentation Fault during running radtest and freeradius

21 Aug 2010

      Hello,

I use Freeradius 2.1.10 (built from the git branch 2.1.x). I just 
configured it with one user (testing, password) and a shared secret 
(testing123) and didn't change anything else.
I run freeradius -X (Ubuntu 10.04) and when it receives a request 
(radtest testing password 127.0.0.1 0 testing123) I get following crash 
(sorry for the long log).

Any ideas how to fix it or where the problem is?

Thanks in advance!
