--- Comment #8 from hsteoh at qfbox.info ---
The specified PR does not fully fix the problem.

Proof:
--------
bool schrodingersCat() @safe {
        union Box { bool b; ubyte y; }
        Box u;
        u.y = 2;
        return u.b;
}

void main() @safe {
        import std.stdio;
        bool b = schrodingersCat();
        if (b) writeln("alive");
        if (!b) writeln("dead");
}
--------

Output:
--------
alive
dead
--------
