Be advised, the C/C++ standards leave the behavior of `malloc` implementation-defined in the case of a zero-sized allocation, and they are allowed to return a null pointer or to return a non-null pointer that is not distinct from other zero-sized allocations.  Consider allocating at least a single byte.
