Hi Mr. Finlayson,

I am sending you link to a docker container, containing the 
aforementioned crashing version, where the bug is reproducible.

The Live555 project was built with GCC, debug mode, ASAN+UBSAN.

In one terminal instance (tmux is installed in the container) you can in 
the testProgs directory run  ./testOnDemandRTSPServer 8554

In a second terminal instance you can run the script run-1 and run-4 
while in the experiments folder. The first instance should display the 
error that has been discussed.

The ASAN options are a little less verbose but you can modify it to make 
it fully verbose.

Yours sincerely,

Martin Mirchev
