https://github.com/jgaeddert/liquid-wlan/blob/524a5fcce03580112f45f2a0faff6793c7244827/src/wlan_fec.c#L222 Guess, there is a segfault. Function wlan_update_viterbi27_blk reads twice per step enc_bits array, which is 2 8 _dec_msg_len bytes length. Also there is a segfault on https://github.com/jgaeddert/liquid-wlan/blob/524a5fcce03580112f45f2a0faff6793c7244827/src/wlan_fec.c#L223 I guess, the real nbits argument is equal 8 * _dec_msg_len.

Yeah, valgrind is showing a bunch of memory errors. I'll dig into it a bit.
