From a code skim, not sure how this is really intended to work: I think rtpstream_shutdown sets the exit_flag on every thread to 1, then immediately frees the memory. But rtpstream_playback_thread keeps references to threaddata for some time after exit_flag is last checked. Naively it looks like a race condition and is fundamentally unsafe.
But I don't seehow the timeout for a select call in rtp_playrtptask would affect this, so clearly I don't understand the area enough :-)

Consistently reproduces with high enough call rate (e.g. 10 cps for me). Doesn't repro with 1cps. Intermittent at in between call rates.
