MSVC fails to compile
#include <iostream>
template<int N, int = N>
struct A;
template<int, int V>
struct A{static constexpr int VALUE = V;};
int main() {
A<1> a;
std::cout << a.VALUE;
}
It was a bug in MSVC manifested up to compiler version 19.22, and fixed in 19.23. Demo: https://gcc.godbolt.org/z/occvKEfc3
