I would please like some help understanding why the following code does not compile in MSVC (/std:c++20) but does in GCC and Clang. Seems to be related to the constexpr constructor maybe.

#include <iostream>
#include <array>


class TestX
{
bool GetA(char * outVal, unsigned int outValLen) {(void)outVal, (void)outValLen; return false;}

struct SupportedParam
{
    using GetParamFunc = bool (TestX::*)(char * outVal, unsigned int outValLen);
    constexpr SupportedParam(GetParamFunc gp) : GetParam(gp) {}
    GetParamFunc GetParam;
};

static const auto & SupportedParameters()
{
    static constexpr std::array<SupportedParam,1> t =  
    {
        SupportedParam(&TestX::GetA)
    };
    static_assert(t[0].GetParam == &TestX::GetA);
    return t; 
};

public:

void Print()
{
    for(auto & x : SupportedParameters())
    {
        std::cout << (this->*x.GetParam)(nullptr, 0);
    }
}
};


int main(void)
{
    TestX x;
    x.Print();
}
