Excerpt:

using Result =
    outcome::result<std::tuple<int, std::string>, InHouseErrorz *, MyNVP>;

auto foo() {
    Result r{1, "a"};
    // r = nullptr; //< UNCOMMENT to eliminate warning
    r = {2, "b"};
    return r.assume_value();
}

Very likely that this is a GCC issue (in fact, can't be reproduced in trunk). Yet, it is a curious phenomenon and causing production hassle with our boost upgrade. I am wondering if this is an expected change with later Outcome versions, or worse and crucially if the usage in the reproduction code is somewhat making incorrect assumptions.

Or, if there is confirmation this is just a silly GCC bug, it'd be a good enough resolution.

thanks
