--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced and cleaned up testcase:
```
template <int> struct int_vector_width {
  enum { WORD_BITS, ELEMENT_BITS };
};
template <int t_bits> struct int_vector_trait {
  enum { ELEMENT_BITS = int_vector_width<t_bits>::ELEMENT_BITS };
  void push_back()
    requires(0 != ELEMENT_BITS)
    ;
};

void f() {
  int_vector_trait<8> vec;
  vec.push_back();
}
```

Confirmed.
