Hi Tom, thank you for your fast reply. Indeed updating to a newer version of boost (I moved from 1.46 to 1.53) seems to fix both of the issues. I repeated make test for 10 times and both tests (as well as all others) ran through without issues every time. Before I hat to retry only once or twice to get a hangup. However I am still curious to learn how flowgraph start/stop works for asynchronous blocks, as they don't have a start/stop function, as far as I understood. Can you point me to some documentation or a certain piece of code where I can learn more about this?
