FINAL RESULTS:

data/libtext-metaphone-perl-20160805/metachar.h:9:1:  [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 _codes[26] = {
data/libtext-metaphone-perl-20160805/metaphone_c.c:60:24:  [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).
        max_phonemes = strlen(word);
