Hmmm, I had a simultaneous send/receive app on USRP1 a few weeks ago that SEGVed. I didn't have time to investigate. But perhaps this is the same issue? Could you reduce it to UHD+"stuff"+innocuous sink -- does that work?
Sure can. Graph is as follows: [Null Source] ---> [UHD SINK] [UHD Source] ---> [Null Sink] Results are as follows: Options Block/Generate Options set to QT-GUI : Runs Fine Options Block/Generate Options set to WX-GUI : SEGV Options Block/Generate Options set to No-GUI : SEGV Also added a "NOP" block in-between the sources and sinks, same result.
