The overload resolution error occurs if:
1. some class has user-defined conversion to the reference to a plain type, and
2. there is oveloading between a user-def operator and built-in one, and
3. The built-in operator takes the result of the conversion mentioned
in 1 as an operand.

I've just met with sustaining team. This fix has been backported to
Studio 11 and will be included in the next patch (number 6).
