[asterisk-dev] Asterisk crash

[Dan Cropp]

We have a customer with asterisk 16.17.0 installed.  Every once in a while, we have been seeing a crash.  We have upgraded the version a couple times, but this random crashing issue has been going on for some time.

Over the weekend, it happened again.  This time, I have a .crash file from it.
Put it through apport-unpack and think I have a good CoreDump from it.
Running asterisk 16.17.0 here is what the gdb backtrace is showing.

Program terminated with signal SIGABRT, Aborted.

Any suggestions of what I could try?
