UHD programs immediately exit

I am running a USRP2 with a WBX daughtercard using the UHD drivers. I
had
the entire setup working about two weeks ago. Now whenever I run a
flowgraph
with a UHD sink, I get the following output and then the program exits.

Done

I’m able to connect to the USRP2 using the uhd_find_devices and
uhd_usrp_probe commands. Does anybody know what would cause the programs
to
immediately exit?

What changed? OS upgrade, gnuradio update, uhd update etc…?

That exit could be a segfault from an ABI mismatch. I would try
rebuilding gnuradio. Just to be sure, clean your installs and rebuild
both libraries.
