Hello,
When running 'radiusd -X' (version 1.1.5) it ends with a
segmentation fault. I did not make any changes to the default
configuration files, just tried to execute the steps in section 2 of
the 'INSTALL' file.
Here is the output of 'radiusd -X':

I am not too lazy to modify the configuration files but I thought it
would be best to run with a default set; is this wrong? Should I first
modify the configuration files and then try again?
many thanks, Felix
