--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, here is a testcase that does not error out before the ICE:
```
namespace std {
template<typename T> struct tuple_size;
template<int, typename> struct tuple_element;
}
struct A {
template <int I> int get() { return 1; }
};
template<> struct std::tuple_size<A> { static const int value = 3; };
template<int I> struct std::tuple_element<I,A> { using type = int; };
struct B {
A *begin();
A *end();
};
void f (B a)
{
#pragma omp for collapse(2)
for (auto [i, j, k] : a)
for (int l = i; l < j; l += k)
;
}
```
Note -fopenmp -Wall is needed to get the ICE.
