FINAL RESULTS:

data/r-cran-mets-1.2.8.1+dfsg/src/tools.cpp:259:18:  [1] (buffer) equal:
  Function does not check the second iterator for over-read conditions
  (CWE-126). This function is often discouraged by most C++ coding standards
  in favor of its safer alternatives provided since C++14. Consider using a
  form of this function that checks the second iterator before potentially
  overflowing it.
