[Bug-gnu-radius] SEGFAULT on syntax error in raddb/config

[Maurice Makaay]

Hi,

I have found a SEGFAULT problem on a certain config file syntax problem.
I haven't tracked it down in the source code, but here are the problem
details (BTW I ran into this problem the moment I forgot a semi-colon in 
my rewrite block):

minimal config I can reproduce the problem with:
----------------------------------------------------------------------
rewrite {
        load "rewrite.internlnet";
}
                                                                                
logging {
        channel debug {
                file "radius.debug";
        };
};
                                                                                
auth {
        listen 127.0.0.1:1812;
};
----------------------------------------------------------------------

Last bit of truss output:

I hope this is useful.
