How to enable debugging? I manually added in rcorder.c:

#define DEBUG 1
#ifdef DEBUG
int debug = 1; /* changed to from 0 to 1 */

Maybe above is wrong.

After compile when I run rcorder:
...
do_file on /usr/local/etc/rc.d/start-dg.sh.
rcorder: Circular dependency on file `/usr/local/etc/rc.d/start-dg.sh'.
rcorder: Circular dependency on provision `squid' in file 
`/usr/local/etc/rc.d/start-dg.sh'.
next do: nuking /usr/local/etc/rc.d/start-dg.sh
next do: /etc/rc.d/LOGIN
nuking /etc/rc.d/LOGIN
next do: /usr/local/etc/rc.d/squid.sh
nuking /usr/local/etc/rc.d/squid.sh
next do: /usr/local/etc/rc.d/start-dg.sh
nuking /usr/local/etc/rc.d/start-dg.sh
Segmentation fault (core dumped)

Here is trace:

Core was generated by `rcorder'.
