--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is unrelated to generic lambdas and can reproduce with just a templated
function:
```
struct y
{
  template<int>
  void foo() const {}
};

template<typename T>
struct pair
{
  T a, b;
};

template<class t>
void bar(void)
{
    pair<y> x[10];
    for (auto const &[a, b] : x)
      a.foo<0>();
}
```

Note the forall loop is required.
I wonder if that is because begin and end are considered type depdent ...
But not using structured binding, GCC does not considered them as type depdent.
Confirmed.
