[SR-Users] Core dump on diameter CCR request

[Daniel-Constantin Mierla]

Hello,

get the full backtrace with gdb from the core file -- it should reveal
where the crash happened.

Also, it might be good to open an issue in bug tracker from
github.com/kamailio/kamailio in order to track it properly.

Cheers,
Daniel
