FINAL RESULTS:

data/r-bioc-genefilter-1.72.0/src/rowttests.c:14:1:  [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 errmsg[256];
data/r-bioc-genefilter-1.72.0/src/rowttests.c:178:8:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	      sprintf(errmsg, "length(fac)=%d, ncol(x)=%d, should be the same.",
