Rather than a try/catch block, I just changed my code from
usrp->set_time_source(val,mboard);
to
if (usrp->get_time_source(mboard)!=val)
usrp->set_time_source(val,mboard);
This seems to handle it for me. I also did the same for
usrp->set_clock_source() because I was experiencing some long delays (but
not crashing).
