Astobj2.c: FRACK!

Hi,
I have Asterisk 13.13 with PJSIP.
I have cronjop, it reconfigure same IP address for box every day.
But sometimes after the cronjop work I receive this log and Asterisk automaticly restart yourself. Do you have any idea about it?

Memory corruption. These are often difficult to debug because the crash usually happens some time after the original corruption, however, for all crashes, see: https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace

This was likely fixed as of Asterisk 13.14.0[1].
