[Ccrtp-devel] Segfault running rtpsend [ccrtp-0.7.3]

[Phil Kerr]

Hi,

After a clean install of Common C++ [1.6.4] and ccrtp-0.7.3, running
rtpsend causes a segmentation fault.

My system is a stock RH 7.2.

rtplisten receives the sent RTP packet ok.

The last few lines from running rtpsend with strace can be found below.

Compile and make look fine (apart from 2 warnings from libtool relating
to -release and -version-info).

Bug ?

Regards

Phil
