Consider the following C++ code example:

#include<iostream>

class B {
public:
    int val;

    B(int v):val(v){
        std::cout<< val << "n";
    }
};

template<typename T>
class A {
public:
    static B b;
};

template<T>
typename B A<T>::b = B(1);

int main() {
    A<int>::b.val;
    return 0;
}

On GCC 11.4.0, build with g++ main.cc -g got output 1.

On Clang 14.0.0, build with clang++ main.cc -g got segfault.

Ubuntu 22.04.4 LTS

Cannot understand the reason of such behavior, would be very grateful for any help.
