Discussion:

The effects clause for the basic_string template ctor in 21.3.1, p15 leaves out the third argument of type Allocator. I believe this to be a mistake.

Proposed resolution:

Replace

> -15- Effects: If `InputIterator` is an integral type, equivalent to

> > `basic_string(static_cast<size_type>(begin), static_cast<value_type>(end))`

with

> -15- Effects: If `InputIterator` is an integral type, equivalent to

> > `basic_string(static_cast<size_type>(begin), static_cast<value_type>(end), a)`
