Do you start ChildApp2 from a thread? If so, do not do it, it doesn't work. If not, I can't see the bug. The main threads starts Childapp2, this one starts ChildApp, this creates the threads. Since poll() should only be called from the main thread, the main thread can't do it until the constructor is done and t1 and t2 are there. >> > - The second issue is with stop_osd.

Strange, maybe it tries to restart the osd and crashes? In childapp.ChildApp2, add some print statement at the stop and restart osd functions to see if they are called correct. > NOTE: I don't have LIRC, just the keyboard.
