FINAL RESULTS:

data/osmcoastline-2.2.4/src/options.cpp:57:23:  [3] (buffer) getopt_long:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
        const int c = getopt_long(argc, argv, "b:c:idhlm:o:p:rfs:S:vV", long_options, nullptr);

  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).
