With the following condensed testcase I get the failure even earlier:
: Search converges between 2004-08-22-trunk (#521) and 2004-08-23-trunk (#522).
========================================
struct A
{
A& operator= (const A&);
};
struct B
{
A a;
B& foo()
{
bool b;
if (b) return *this;
return *this;
}
};
void bar()
{
B().foo().a = A();
}
========================================
Just compile with "-O" or higher.

I think this is latent bug in the tree-ssa optimization as the two dates mine and the ones which Volker
reports is both when &a->b is no longer lowered. (after the first date I had to revert the patch because
it causes other problems).

The problem is that when we do replace_exp_1 from propagate_value, we don't fold &((&a)->b) to
&(a.b).

Here is another example which happens also for C:
struct A { int i; };
struct B { struct A a; };
void f(struct A*, struct A*);
#define bool _Bool
void bar(bool b)
{
struct B * D1601;
struct A D1576;
struct A * D1593;
struct B * D1592;
struct B D1575;
D1575 = (struct B){};
if (b) D1592 = &D1575; else D1592 = &D1575;
D1593 = &D1592->a; // <-- we are prograting &D1575 into here.
D1576 = (struct A){};
f (D1593, &D1576);
}

Indeed, it triggers several times on my codes alone. It would be good if someone cared
about this particular PR rather quickly...

Patch in testing. kill_redundant_phi_nodes is doing the job of CCP, but it
doesn't know how to fold statements properly. There's two fixes we can try: (1)
paper over the problem by teaching k_r_p_n to fold statements, (2) do this
properly in CCP.
Option 2 may mean scheduling CCP more often, but it's preferred and cleaner. If
that proves too invasive for 4.0, I will go with option 1.
