--- Comment #14 from David Manuelda <stormbyte at gmail dot com> ---
It is worth to notice that this bug propagates to C++ whenever an object uses
an int that increments but is never used, like the following example:

class Test{
        public:
                Test() { i = 0; i++; }
        private:
                int i;
};

int main(int, char**) {
        Test unused;

        return 0;
}
