Subject: OT: PJSIP: Segmentation fault
Hi all,
I'm trying to test pjsip-0.9.0 on a Debian with vanilla kernel 2.6.25.9
(without IPv6 support).
I'm posting my problem to this mailing list in the hope that some kernel
guru helps me shed a little light on the problem I'm experiencing, which
- I think - is closely related to Linux network internals.
I'm getting a Segmentation fault but I'm not able to determine the cause.
Avoiding to call pj_enum_ip_interface() completely solves the problem.
Briefly:
I've double-checked the parameters passed to that function; I've printed
messages to standard output to determine where the error occurrs, but it
seems that the cause is not inside the function...
Can you spot anything wrong in the following strace log?
