 Hi,

 After I apt-get update && apt-get upgrade my Raspberry Pi, Tor doesn't
 work any more. What happen is :
 root at raspberrypi:/opt/cjdns# /etc/init.d/tor start
 *** stack smashing detected ***: /usr/sbin/tor terminated
 /etc/init.d/tor : ligne 111 : 29830 Abandon                 $DAEMON
 $VERIFY_ARGS > /dev/null
 Checking if tor configuration is valid ... failed!
 *** stack smashing detected ***: /usr/sbin/tor terminated
 /etc/init.d/tor : ligne 111 : 29836 Abandon                 $DAEMON
 --verify-config 1>&2

 On the advice of sysrqb, I put DisableDebuggerAttachment 0 in my torrc
 file.
 Then :
 root at raspberrypi:/var/log/tor# gdb tor
