This flowgraph is based on the example in the PDU to Stream documentation. The difference is that now 'N' is now a formula instead of a constant ( int(samp_rate*tx_dur) )
As soon as I enable the one disabled block then gnuradio will crash with only a X window system error. And as far as I can tell this only happens when N is variable. VEC is defined as `pmt.init_f32vector( N, np.arange(N) )` [image: image.png]
