[Live-devel] Crash in RTSPServer.cpp

[Jeremy Noring]

We have a crash in our RTSP server (implemented with Live555) that
reproduces when streaming the same session to multiple RTP-over-TCP
clients.  Here's the callstack:

Program terminated with signal 11, Segmentation fault.

(gdb)

The callstack is a bit odd because of optimiztion, but it makes sense going
through tcpReadHandler.  are there any known issues from requesting multiple
RTP-over-TCP streams from the same session?  (also, our client is based on
openRTSP--so Live555 on both sides).
