A flow graph that used to work in Gnuradio 3.7 now fails in 3.7.2.1
I've isolated it to the QT GUI Sink component, which causes the flowgraph to
immediately
aborts with a segmentation fault.
Core was generated by `python ./top_block.py'.
Program terminated with signal 11, Segmentation fault.

Sorry - don't have symbol generation enabled....
If that QT GUI Sink is replaced by QT GUI Frequency Sink then everything runs
OK.
Is this a known issue, or has the QT GUI Sink been deprecated? It appears on
the lis
of choosable blocks in Gnuradio Companion.
I did not find an issue in the issue tracker related to this specific block.
