I found a bug in the GR runtime.  Here's a simple script to demonstrate it.

AFAIS, the problem is that GNU Radio doesn’t connect message ports when restarting a flow graph.

If you add blocks with message ports, as you do during reconfiguration, they never get connected.

If you add this loop:

https://github.com/gnuradio/gnuradio/blob/master/gnuradio-runtime/lib/flat_flowgraph.cc#L78

also at the end of the merge_connections() function it works for me.

Best,

Bastian
