FINAL RESULTS:

data/ucimf-chewing-0.3/src/chewing.cpp:21:2:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
	char output[outbuf_len];
