        <pre>I'd expect something like the following to be possible (wrapping realloc).
It seems not to work.

#include <stdlib.h>

void *my_realloc(void *ptr, size_t size)
  __attribute__((ownership_takes(malloc,1)))
  __attribute__((ownership_returns(malloc,2)));

void
test()
{
  void *ptr = malloc(10);
  ptr = my_realloc(ptr, 11);
  free(ptr);
}</pre>
