[arm-allstar] Asterisk crashing when Echolink connected

[Matt]

I've set up a new node and all is working fine apart from the Echolink side.

Whenever I try and connect the node to an echolink node, Asterisk 
randomly crashes and restarts. After a little investigation, I found 
this in the journal..

May 29 14:25:25 allstar rc.local[194]: /usr/bin/safe_asterisk: line 
125:  1765 Segmentation fault      (core dumped) nice -n $PRIORITY 
${ASTSBINDIR}/asterisk -f ${CLIARGS} ${ASTARGS} &> /dev/${TTY} < /dev/${TTY}
May 29 14:25:25 allstar rc.local[194]: Asterisk ended with exit status 139
May 29 14:25:25 allstar rc.local[194]: Asterisk exited on signal 11.
May 29 14:25:25 allstar rc.local[194]: Automatically restarting Asterisk.
May 29 14:25:25 allstar systemd-coredump[1855]: Process 1765 (asterisk) 
of user 0 dumped core.

Has anyone seen this before and is there a fix?

Thanks,

Mat
