This ICE also hits in the boost testsuite:

markus@x4 more % cat test.ii
struct B
{
    virtual void test_suite_finish ();
};
void
fn1 (B & p2)
{
    fn1 (p2);
    B & a = p2;
    a.test_suite_finish ();
    B b;
    fn1 (b);
}

markus@x4 more % c++ -O3 -c test.ii
test.ii:13:1: internal compiler error: in ipa_get_parm_lattices, at
ipa-cp.c:263
 }
