        <pre>ReturnPtrRange doesn't like the past-the-end pointer returned by std::end:

#include <iterator>
void foo() {
    int arr[5] = {};
    std::end(arr);
}

which gets me a:

    warning: Returned pointer value points outside the original object
(potential buffer overflow) [clang-analyzer-alpha.security.ReturnPtrRange]

in the implementation of std::end(T(&array)[N]) ("return __array + _Np;")</pre>
