valgrind says:

CreateMediaStream TestChannel[ Call[C02e1f8fb1]-EP[L22cf95bf2] - 0x3c0550f0 ] assert.cxx(112) PWLib Assertion fail: Attempt to do simultaneous reads from multiple threads: os_handle=24, thread ID=0x1f385700, file ptlib/unix/channel.cxx, line 110OnOpenMediaStream recording media from local

I have the latest version of ptlib_dev, any ideas ?
