Trying to run a C++ based flowgraph and occasionally getting a
segfault/coredump. Finally, was able to capture the stack trace, and I am not
sure what to make of it. I //think// that this is all UHD, and not my app, but
I find that hard to believe. Here is that core dump, any thoughts on what is
causing this and if there is any way for more to gracefully recover from it?
This was using a single N320, gnuradio v3.8, and UHD 4.1.0.5.
