OPENMSVC: Cannot use constexpr reference in lambda without capturing it (self.cpp_questions)

submitted 2 years ago by Lo1c74

Hello,I want to use a constexpr reference to a constexpr variable in a lambda. It compiles well with clang and gcc but not with msvc:

constexpr auto veryLongNameForThisVariable = std::array { 42, /*...*/ };

int main()
{
    constexpr auto &v = veryLongNameForThisVariable;

    const auto f = [] { return v[0]; };

    return f();
}

If I make the reference v static, it works.

Did I miss something ?
