Suggested resolution:

Change in 7.6.1.3 [expr.call] paragraph 7 as follows:

If the function is an implicit object member function, the this implicit object parameter of the function (7.5.2 [expr.prim.this]) is initialized with a pointer to the object of the call, converted as if by an explicit type conversion (7.6.3 [expr.cast]).

Subclause 7.6.1.3 [expr.call] paragraph 7 specifies:

If the function is an implicit object member function, the this parameter of the function (7.5.2 [expr.prim.this]) is initialized with a pointer to the object of the call, converted as if by an explicit type conversion (7.6.3 [expr.cast]).

The term "this parameter" is undefined.
