--- Comment #4 from piersh at hotmail dot com ---
is it related to nested classes? this reproduces the issue: uncomment line =
9 to
repro:


#include <unordered_map>
#include <memory>

struct key {};

struct my_hash
{
    my_hash() {}
    //my_hash(int i =3D 42) {}  // <<-- uncomment for bug
    std::size_t operator()(const key &ep) const { return 0; }
};

struct foo
{
    foo();
private:
    std::unordered_map<key, int, my_hash> things_;
};

foo::foo() {}=
