--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Since r12-8066-g4822108e61ab8790, reduced test-case:

$ cat pr106925.ii
struct Foo;
template <int _Nm> struct __array_traits { typedef Foo _Type[_Nm]; };
template <int _Nm> struct array {
  typename __array_traits<_Nm>::_Type _M_elems;
};
template <int size> struct MyVector { array<size> data{}; };
struct Foo {
  float a{0};
};
void foo(MyVector<1> = MyVector<1>());
