[Bug c++/32944] operator= not ambiguous overload but does not compile

--- Comment #2 from Dallas at ekkySoftware dot com  2007-08-01 00:14 ---
The reason I was passing the reference and not the value is because is some
circumstances I can change the value of the parameter. Using the const keyword
prevents me from calling methods that can change the value – even if in this
example they do not.

Thanks,
