[Bug tree-optimization/15874] [3.5 Regression] ICE: in create_temp, at tree-outof-ssa.c:143 with -O2 (C++)

Note that Serge's testcase crashes in
replace_ssa_names, at tree-ssa-copy.c:73

Here's an even shorter version of Serge's testcase:

===========================================
void foo();

struct A
{
    int i;

    A() : i(0) {}
    ~A() { if (i) foo(); }
    void bar(A &a) { a.i = 1; }
};

void quus()
{
    A a1, a2;
    foo();
    a1.bar(a1);
}
===========================================

Here's a testcase that crashes in the same spot as the
original testcase, namely in create_temp, at tree-outof-ssa.c:143

===========================================
void foo();

struct B
{
    ~B();
};

struct A
{
    int i;
    B b;

    ~A() { foo(); }
    int bar() const { return i ? i+i : 0; }
};

int quus()
{
    A a1;

    foo();
    while (1)
    {
        A a2;
        if (a2.bar()) return 0;
    }
}
===========================================
