Thank you for reply, Benny!
Now i do these things:
1. run pjsua from gdb debugger
2. connect mic port to output in pjsua ("cc 0 0")
3. give some load (using "stress -c 1" command) and hit a segfault
(but sometimes just the sound stops with no segfault)
Here how it looks:
(gdb) run
Starting program: /pjdebug/pjsua

Is that enough to debug?
BTW, when connecting ports using "cc 0 0" there are also strange warnings,
but still it connects ok and a hear myself:

Success
Do i have to worry about there warnings?
