A backtrace provides information about what was happening at the time of a crash. There is no guide on how to fix what a backtrace shows because it depends on what it is and is usually the first step to understanding a crash, you usually have to dig deeper. In your case we asked the system to resolve something and it crashed. I don’t know why it did that. What version of Asterisk? What Linux distribution or environment? What CPU?
asterisk-14.0.1 centos 7.5 Intel® Xeon® Platinum 8163 CPU @ 2.50GHz
Asterisk 14 is no longer supported, and CentOS is a platform we regularly test on. I’d suggest trying a supported version[1] before pursuing it any further.

The abort is due to memory corruption and the actually failure an be in a completely different thread from that which eventually crashes.
