Does *not* reproduce on trunk
Does reproduce using gcc-4_7 (r197167)
Test case:
struct Iter
{
int& operator* ();
void operator++ ();
};
bool operator!= (Iter &, Iter &);
struct Container
{
Iter begin () const;
Iter end () const;
};
struct J
{
virtual J *mutable_child ();
};
struct M
{
M (const Container &);
J ns_;
};
namespace
{
J MakeNamespace (const Container &src)
{
J a;
J *b = 0;
for (const int &c: src)
b = b ? b->mutable_child () : &a;
return a;
}
}
M::M (const Container &ns):ns_ (MakeNamespace (ns))
{
}
