[sr-dev] Re: [kamailio/kamailio] Kamailio core dump v5.6 with cncxx module (Issue #3859)

You still didn't get the gdb backtrace from the core file. Once Kamailio crashed and dumped the core file, you have to run:

``` gdb /usr/local/sbin/kamailio /path/to/core ``` Then inside it run `bt` or `bt full`.

It should output something like `Debugging Data` from the issue:

You have to locate where the core file is written, which can be specific to the OS. Search the web for `where is core file written on Debian 12` (replace `Debian 12` with your OS name and version. Once you know the path of the core file, replace `/path/to/core` accordingly in the command above.
