------- Comment #3 from paolo dot carlini at oracle dot com  2009-01-30 16:57 -------
In the meanwhile the patch for PR38503 has been installed and unfortunately I
have to report that this issue seems indeed different, eg, this testcase is
still not fixed on x86_64-linux:

#include <string>
#include <list>

class A;

class B {
public:
    void foo(A&);
    std::string s;
};

class A {
public:
    A& qaz() {
        l.push_back( new A() );
        return *l.back();
    }
    std::list<A*> l;
};

void bar()
{
    A a;
    B b;
    b.foo(a.qaz());
}
