FINAL RESULTS:

data/camlbz2-0.6.0/c_bz.c:174:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(String_val(result), unused, nunused) ;
data/camlbz2-0.6.0/c_bz.c:267:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(String_val(result), dst_buf, dst_len);
data/camlbz2-0.6.0/c_bz.c:320:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(String_val(result), dst_buf, dst_len);
data/camlbz2-0.6.0/io.h:37:3:  [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.
