FINAL RESULTS:

data/ruby-strptime-0.2.5/ext/strptime/strftime.c:159:2:  [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(p, mon, 3);
data/ruby-strptime-0.2.5/ext/strptime/strftime.c:204:2:  [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(p, RSTRING_PTR(fmt) + off, len);
data/ruby-strptime-0.2.5/ext/strptime/strptime.c:133:17:  [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).
	    size_t l = strlen(month_names[i]);
