Hello Ross,
I am sorry, it is not fixed yet.
Analysis: Here is the modified code in RTSPClient::connectionHandler1.
...
// The connection succeeded. If the connection came about from an
attempt to set up RTSP-over-HTTP, finish this now: if
(fHTTPTunnelingConnectionIsPending && !setupHTTPTunneling2()) break;
// Note: Normally "fOutputTLS" == "fInputTLS" here, except when
we're connecting // to the second (i.e., "POST") connection when
doing RTSP-over-HTTP: if (fOutputTLS->isNeeded) {
// We need to complete an additional TLS connection:
int tlsConnectResult = fOutputTLS->connect(fOutputSocketNum);
...
Before fOutputTLS->connect(...) is called, it is already used in
setupHTTPTunneling2() 6 lines above, stack frame #5 - > SIGSEGV
