Hi Ravi,
The same problem happens in several places. I also have to fix
H223LogicalChannel::~H223LogicalChannel()
PVCommsIONodePort::~PVCommsIONodePort()
I have tried a similar method to fix this before, but
pv2way_omx_engine_test will hang after some more tests, and I'm not
sure if it's related. Will start tracing that. Here is the results
after I set iPortActivityHandler to NULL in all 3 places:
