This is indeed a bug:
| When the value of the expression in a direct-new-declarator is zero,
| the allocation function is called to allocate an array with no
| elements. The pointer returned by the new-expression is non-null.
| [Note: If the library allocation function is called, the pointer
| returned is distinct from the pointer to any other object. ]
