I have a weird problem that I've seen for a while and I've just ignored until now. I've seen this with numerous pieces of hardware, but I am currently using an E320 in network mode. This seems to only happen when I am using RFNoC, so I assumed it was me, but today I was testing with only stock blocks and have the same issue.
The problem is that when I run a GR flowgraph without a GUI in "prompt for exit" mode, it doesn't always seem to exit. I'll hit enter like I am supposed to, but it just hangs until I press ctrl-c. Currently I have an RFNoC:Radio -> DmaFIFO -> GR blocks. I have tested this with different combos of blocks and they all seem to have the same issue. I originally thought it was me or the split stream block, but they are both out of the equation now. Has anyone else seen this issue before? I am running: [INFO] [UHD] linux; GNU C++ version 4.8.5 20150623 (Red Hat 4.8.5-36); Boost_105300; UHD_3.14.1.HEAD-0-g5491b80e and GR: v3.7.13.4
