[SR-Users] Segfault running 3.3.0 with registrar/p_usrloc/path

[Daniel-Constantin Mierla]

Hello,

if you can reproduce it, try to get the core dump, some steps that will 
help getting one easier:

- run as root
- before starting do: 'ulimit -c unlimited'

Retest in order to get the issue again and if you get the corefile, then 
send the backtrace:

gdb /path/to/kamailio /path/to/corefile
bt full

Cheers,
Daniel
