Summary

The following unspecified behaviors are incomplete in Annex J.1, aligned_alloc() is missing in both entries.
— The order and contiguity of storage allocated by successive calls to the calloc, malloc, and realloc functions (7.22.3).

— The amount of storage allocated by a successful call to the calloc, malloc, or realloc function when 0 bytes was requested (7.22.3).
The following undefined behavior bullet is incomplete in Annex J.2, aligned_alloc() is missing.
— A non-null pointer returned by a call to the calloc, malloc, or realloc function with a zero requested size is used to access an object (7.22.3).
The following implementation-defined behavior bullet is incomplete in Annex J.3.12, aligned_alloc() is missing.
— Whether the calloc, malloc, and realloc functions return a null pointer or a pointer to an allocated object when the size requested is zero (7.22.3).

— The order and contiguity of storage allocated by successive calls to the calloc, malloc, realloc, and aligned_alloc functions (7.22.3).
