FINAL RESULTS:

data/libtabixpp-1.1.0/tabix.cpp:14:12:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
    strcat(strcpy(fnidx, cfilename), ".tbi");
data/libtabixpp-1.1.0/tabix.cpp:14:5:  [2] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused). Risk is low because the
  source is a constant string.
    strcat(strcpy(fnidx, cfilename), ".tbi");
data/libtabixpp-1.1.0/tabix.cpp:13:34:  [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).
    char *fnidx = (char*) calloc(strlen(cfilename) + 5, 1);
