FINAL RESULTS:

data/fizmo-console-0.7.13/src/fizmo-console/fizmo-console.c:393:21:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
      line_length = atoi(argv[i]);
data/fizmo-console-0.7.13/src/fizmo-console/fizmo-console.c:158:16:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  if ((input = fgetc(stdin)) == EOF)
data/fizmo-console-0.7.13/src/fizmo-console/fizmo-console.c:175:18:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if ((input = fgetc(stdin)) == EOF)
data/fizmo-console-0.7.13/src/fizmo-console/fizmo-console.c:200:12:  [1] (buffer) getchar:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  result = getchar();
