We have plenty of sorta generic functions, that allocate memory with
some generic name for debugging. When such a function is called and the
memory leaks, it may be unclear which call to it allocated the unfreed
memory (and thus which execution path leads to the leak).
The added function is only available if `NDEBUG` is not defined.
