[USRP-users] RFNoC AddSub example error

Howdy,

When I try to run the rfnoc_adder.grc example, it throws this error:

thread[thread-per-block[2]: <block uhd_rfnoc_AddSub (1)>]: RuntimeError: On node 0/AddSub_0, input port 0 is already connected.

This is with a fresh install of uhd rfnoc-devel branch and the standard rfnoc image. Other RFNoC blocks seem to work fine.
Do you know what might be wrong?

Thanks,
Sam
