[Live-devel] Crash in RTSPServer.cpp

Not a lot, unfortunately.  Can you run something like "valgrind" that 
will give you more detailed information about where/why the crash is 
occurring?

I suspect that the problem has to do with the modifications that we 
made in version 2010.03.14 to handle RTSP commands sent within a 
RTP-over-TCP session.  If that's the case, I would not expect to see 
problem occur if you used only RTP-over-UDP sessions.  It's probably 
worth testing this, though.

It would be nice to find a simple, repeatable sequence of client 
operations that cause the crash.  E.g., does crash ever happen if 
there are two complete "DESCRIBE, SETUP, SETUP, PLAY, TEARDOWN" 
sequences in order (i.e., not overlapping), or does it occur only 
when two such sequences overlap?  Once you've found a repeatable 
situation that causes the crash, then you could also test with 
RTP-over-UDP, and with "reuseFirstSource" set to False.
