FINAL RESULTS:

data/jack-delay-0.4.2/source/jack_delay.cc:173:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf (b, "%s:out", jack_name);
data/jack-delay-0.4.2/source/jack_delay.cc:182:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf (b, "%s:in", jack_name);
data/jack-delay-0.4.2/source/jack_delay.cc:83:17:  [3] (buffer) getopt:
  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.
    while ((k = getopt (ac, av, options)) != -1)
data/jack-delay-0.4.2/source/jack_delay.cc:139:5:  [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           b [1024]; 
data/jack-delay-0.4.2/source/jack_delay.cc:210:2:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
	usleep (250000);
