The bug occurs very often, log file doesn't show anything useful.

There is an assertion that the semaphore isn't released.
In OpalAudioJitterBuffer::WriteData, m_closed is true.
OpalRTPSession is valid, OpalRTPSession::SyncSource is valid.

Log file has attached.

Another log file is here.
The crashed thread id is 13268, but I see only 1 message for this thread in the log file:

RTP:13268 rtp_session.cxx(2475) 0000000000001 RTP Session 1, thread started

Is this still occurring?

[Robert Jongbloed]

No answer on if still occurring. No other reports so closing.
