Hi Werner,
Can you explain more about your view or give a link if it's an accepted
opinion. I'm used to an implementation stating its choices from those
given by a C standard, e.g.
(42) Whether the calloc, malloc, realloc, and aligned_alloc functions
return a null pointer or a pointer to an allocated object when
the size requested is zero (7.24.3).
I'd call malloc(0) and know it's not undefined behaviour but one of
those choices.

Cheers, Ralph.
malloc(0)
isn't undefined behaviour but implementation defined.
In modern C there is no difference between those two concepts.
