graph intermittently stalls with tbb::flow::async_node

[Marc_R_5]

It is either all or nothing.  

Running  tbb43_20150611oss/src/test/test_async_node.cpp  reproduce the issue.  Either the test will run to completion or will never complete.   When the worker thread calls async_try_put() it does not always wake up the next node connected to it.

Hello Marc,

how many core you are running the test on?

Hello Vladimir, 

Good question!  I was running the test with only 1 core active.  Running the same test with 4 cores did not reproduce the stall issue.

Thanks,

Marc
