[Linphone-users] segfault in ortp-0.10.0

[Andre Noll]

Hi Simon,

I'm getting this with ortp-0.10.0:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1214494096 (LWP 23756)]

The segfault is due to session->sd being NULL. The patch below fixes the
problem for me.

Have fun
Andre
