--- Comment #4 from janus at gcc dot gnu.org ---
Producing a dump via -fdump-tree-original shows what's going on in the case of
comment #3, namely: 'e' is being deallocated before being passed to 's1':


      if ((struct t1[0:] * restrict) e.data != 0B)
        {
          __builtin_free ((void *) e.data);
          (struct t1[0:] * restrict) e.data = 0B;
        }
      s1 (&e);


That is correct so far. However, what is missing is the deallocation of e's
components. Those are only auto-deallocated at the end of the subroutine
'leak'.
