Andrew's example in comment #26 is broken.
ret.cd is set to 2 and therefore we have a.b.cd!=1 which triggers the abort.

Nevertheless, here's a reduced testcase derived from comment #25:

================================
void abort(void);

typedef struct { int i; } A;

A foo(void)
{
  A a = { 1 };
  int j;
  for (j=0; j<2; j++) ;
  return a;
}

void bar(A *p)
{
  *p = foo();
}

int main(void)
{
  A a;
  bar(&a);
  if (a.i != 1)
    abort();
  return 0;
}
================================
