FINAL RESULTS:

data/ruby-sequel-pg-1.12.2/ext/sequel_pg/sequel_pg.c:746:3:  [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.
  char buf[64];
data/ruby-sequel-pg-1.12.2/ext/sequel_pg/sequel_pg.c:757:7:  [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(buf, val, len-2);
data/ruby-sequel-pg-1.12.2/ext/sequel_pg/sequel_pg.c:762:7:  [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(buf, val, len-3);
data/ruby-sequel-pg-1.12.2/ext/sequel_pg/sequel_pg.c:767:7:  [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(buf, val, len-4);
