[Live-devel] ProxyServerMediaSubsession Segmentation fault

[Conchi Abasolo]

Hello Ross


Many thanks!!!

I've been testing the new release and it fixes the bug that I reported 
last week. When a BYE is received from the backend, the proxy doesn't crash.
But, once the connection with the frontend client is closed, if you try 
to connect again to the stream source, a new error appears.
You can see below a complete log of a test connecting against a Mpeg4 
stream source (through TCP):
