FINAL RESULTS:

data/libmath-geometry-voronoi-perl-1.3/vdefs.h:115:12:  [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.
extern int getopt(int, char *const *, const char *);
data/libmath-geometry-voronoi-perl-1.3/ppport.h:724:22:  [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).
        STRLEN len = strlen(radix);
