Passing std::array by reference in constexpr constructor results in null data pointer

My class has a constexpr constructor which takes a reference to a std::array. When creating a global constexpr constant of my class and passing an immediate array, the constructor gets a null data pointer from the array reference even though the underlying data exists:

class MyClass {
public:
    explicit constexpr MyClass(const std::array<int, 3> &from) {
        assert(from[0] == 1);           // Ok
        assert(from[1] == 2);           // Ok
        assert(from[2] == 3);           // Ok
        assert(from.data() != nullptr); // Compilation halts here
    }
};

static constexpr MyClass constGlobal{std::array{1, 2, 3}};

Requires C++ 17+

Tested on:

MinGW w64 9.0

ARM gcc 12.2

I would expect the data() pointer to exist considering operator[] works perfectly fine.

EDIT:

The data() pointer does exist. This seems to be an issue with GCC not allowing pointer comparison to temporaries. There still exists a related problem which this simplified example attempted to describe (badly).

Here's the root problem.

EDIT:

Looks like this is the likely gcc bug for comparison of addresses of temporaries in constexpr context:
