alt Hacker News> Noncompliant, since `malloc(0)` is specified to return a unique pointer if it's not `NULL`.
I know I've seen that somewhere, but may I ask what standard you're referring to?

It's POSIX.
> Each [...] allocation shall yield a pointer to an object disjoint from any other object. The pointer returned points to the start (lowest byte address) of the allocated space. If the space cannot be allocated, a null pointer shall be returned. If the size of the space requested is 0, the behavior is implementation-defined: either a null pointer shall be returned, or the behavior shall be as if the size were some non-zero value, except that the behavior is undefined if the returned pointer is used to access an object.
