FINAL RESULTS:

data/zita-convolver-4.0.3/source/zita-convolver.cc:736:10:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	if (n1) memcpy (_time_data, inpd + i1, n1 * sizeof (float));
data/zita-convolver-4.0.3/source/zita-convolver.cc:737:10:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	if (n2) memcpy (_time_data + n1, inpd, n2 * sizeof (float));
data/zita-convolver-4.0.3/source/zita-convolver.cc:807:6:  [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 (outd, _time_data + _parsize, _parsize * sizeof (float));
data/zita-convolver-4.0.3/source/zita-convolver.cc:355:9:  [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 (100000);
