TX/RX and RX2 with same USRP source block

GNU Radio
1

I have received an exception called: “Floating point exception”, I guess
that the reason is because I am trying to use the ports TX/RX and RX2
with an USRP-SOURCE (please review the code below).

Is there any special configuration to use USRP with GNURadio with that
specific configuration?

regards,

Richard
