[Discuss-gnuradio] `s < d_bufsize' failed.

[Charles Swiger]

Any general clues what would be causing: 

python: ./gr_buffer.h:96: unsigned int gr_buffer::index_add(unsigned
int, unsigned int): Assertion `s < d_bufsize' failed.


I'm taking a closer look at atsc_bit_timing_loop.cc|h and trying
gr_sync_decimator in place of gr_sync_block, however that error occurs
with both. It is supposed to be a decimator since the rf in at sample
rate 20e6 and symbols out at 10.76MHz.


Putting in the history=1500 and printing ninput_items_required gets
this:


>>> gr_fir_fff: using SSE
ninput_items_required: 16720
ninput_items_required: 9108
ninput_items_required: 5303
