If I run the test program from that post, it works sometimes, but occasionally an assertion goes off as shown in the terminal output below.
In my own application (a C++ app based on rx_streaming_samples.cc), I'm stepping through a sequence of frequencies. For each frequency, I set the center frequency, start streaming, buffer up some samples, stop streaming, write the samples to disk and go around again. It works for a few frequencies and then (not always on the same iteration) stop_rx_streaming fails. After that, setting the center frequency always fails.
The thread above says the problem was fixed and the fix was moved to the master branch. I'm running gnuradio 3.3.0. Do I need to pull another branch?
