Paragraphs 12 and 25 of 11.4.5.3 [class.copy.ctor] both say that the function
is trivial if it is not user-provided, its declared parameter type is the same as if it had been implicitly declared, and...
However, a non-user-provided function might have more than one parameter if default arguments are used. The phrasing would be better as something like “its parameter-type-list is equivalent to the parameter-type-list of an implicit declaration.” (For consistency, the same phrasing should be used in 11.4.5 [class.ctor] paragraph 5. )
Proposed resolution (June, 2013):
Change 11.4.5.3 [class.copy.ctor] paragraph 12 as follows:
A copy/move constructor for class X is trivial if it is not user-provided, itsdeclared parameter type is the same as if it had been implicitly declaredparameter-type-list is equivalent to the parameter-type-list of an implicit declaration, and if...
