--- Comment #3 from Fedor Chelnokov <fchelnokov at gmail dot com> ---
Even more reduced example. Below program is accepted in Clang and MSVC:
```
template <typename T2>
struct Y {
static constexpr T2 x{0};
};
template<>
constexpr int Y<int>::x{1};
int main() {
static_assert(Y<int>::x == 1);
}
```
but GCC complains:
```
duplicate initialization of 'Y<int>::x'
```
