FINAL RESULTS:

data/r-cran-forecast-8.13/src/etsTargetFunction.cpp:98:5:  [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.
	if(equal) return;
