[USRP-users] problem with RFNoC probing

Could this have something to do with tlast?  I don't feel like it is the 
XML files, so I am limited to looking at the verilog, but it is pretty 
similar to my other blocks, so I am not sure what the problem could be.

It is odd to me that the probing is enough to cause issues, I am not 
sure what all gets executed in Verilog when the probe occurs.
