[Discuss-gnuradio] gr-fec compile failing on Ubuntu 16.04

[Marcus D. Leech]

One of my build-gnuradio users is experiencing the following errors when 
gr-fec is being built:

/home/hugh/build-gnuradio/gnuradio/gr-fec/lib/polar_decoder_common.cc: 
In member function ‘void 
gr::fec::code::polar_decoder_common::butterfly_volk(float*, unsigned 
char*, int, int, int)’:
/home/hugh/build-gnuradio/gnuradio/gr-fec/lib/polar_decoder_common.cc:128:95: 
error: too many arguments to function
 8u_polarbutterfly_32f(llrs, u, block_size(), block_power(), stage, 
u_num, row);

Anyone else seen this?
