You had mentioned that when you "CTRL+C" it worked OK, but when you unceremoniously closed the window, itThe issue isn't duration- its when the flowgraph shuts down- as the other thread from someone else is experiencing- it seems to be when the flowgraph calls lock()/unlock() and stop(). It also only occurs on bi-directional flowgraphs. But I do agree that there's an improper shutdown- though I believe its due to some kind of bug. I can construct a very very very simple flowgraph with a sig source and a scope and have it crash when it shuts down "properly".
didn't.I believe that Gnu Radio itself explicitly sets up a signal handler for that case, to make sure that the destructors are called when you
explicitly ctrl-C out of a flow-graph.But for "window close", it may be the case that WxPython doesn't signal everything to "close thyself in a polite manner".
