[Live-devel] ProxyServerMediaSubsession Segmentation fault

[Conchi Abasolo]

Hello

I'm connecting with a mpeg4 stream over TCP (because i can use UDP), 
using the example live555ProxyServer (using the -t option)
The connection is succesfully and i can see the video transmission, but 
when the backend sends a BYE, the live55ProxyServer crashed after trying 
to close the ProxyServerMediaSubsessions

I would like to know what's triggering this issue and the best solution 
to solve it
Just as a suggestion.... Is it possible that the program was trying to 
use a deleted object or something like?.


Here is the complete log:
