--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
We don't eliminate a malloc that's just used in a conditional, I think there's
a related bugreport with

  p = malloc (n)
  if (!p)
    abort ();
  free (p);

or sth like that where we fail to elide the allocation.  Note in this case
failing allocation _would_ have a side-effect.
