[Live-devel] segfault RtspClient

[Gerald Hansink]

Hi Ross,

we still have the same error (below), I highly recommend Asan, it has
proven to be very valuable locating bugs that are otherwise impossible to
detect.
I remember from my last debugging session that all we do is a call to
Medium::close(ourMediaSession).
Tomorrow I will likely have time to look into the code again, hopefully
I'll learn more.

regards,

Frederik De Ruyck
