Associating a function with a @var{deallocator} helps detect calls to
mismatched allocation and deallocation functions and diagnose them under
the control of options such as @option{-Wmismatched-dealloc}. To indicate
the control of options such as @option{-Wmismatched-dealloc}. It also

allocated dynamically, by @option{-Wfree-nonheap-object}. To indicate
that an allocation function both satisifies the nonaliasing property and
has a deallocator associated with it, both the plain form of the attribute
