[Bug middle-end/21663] New: [4.0 Regression] ICE in assign_stack_temp_for_type

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

void
foo (int x, void *y, void *z)
{
  typedef struct { char val[x]; } T;
  T bar (void *w)
  {
    __builtin_return (w);
  }
  *(T *)y = bar (z);
}

ICEs on at least {i386,x86_64,ppc,ppc64}-linux at any optimization level.
Works with 3.4.3 as well as HEAD.
