FINAL RESULTS:

data/gap-float-0.9.1+ds/src/mpc.c:423:5:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
    strcat(c+slen, CSTR_STRING(FLOAT_INFINITY_STRING));
data/gap-float-0.9.1+ds/src/mpc.c:441:7:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
      strcat(c+slen, CSTR_STRING(FLOAT_I_STRING));
data/gap-float-0.9.1+ds/src/mpfi.c:537:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf(c+slen, "(%s)", CSTR_STRING(FLOAT_INFINITY_STRING));
data/gap-float-0.9.1+ds/src/float.c:60:3:  [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 (p->_mp_d, ADDR_INT(obj), s*sizeof(mp_limb_t));
data/gap-float-0.9.1+ds/src/float.c:94:3:  [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 (ADDR_INT(res), z[0]._mp_d, mpz_size(z)*sizeof(mp_limb_t));
data/gap-float-0.9.1+ds/src/mpfi.c:541:7:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
      sprintf(c+slen, "(%ld)", -exp);
data/gap-float-0.9.1+ds/src/mpfr.c:454:5:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
    sprintf(s+slen,"%ld",exp);
data/gap-float-0.9.1+ds/src/mpfi.c:546:23:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  SET_LEN_STRING(str, strlen(c));
data/gap-float-0.9.1+ds/src/mpfr.c:445:14:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
  int slen = strlen(s);
data/gap-float-0.9.1+ds/src/mpfr.c:455:12:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
