Looking at N2284, 31.8 [re.regex], p3 basic_regex class template synopsis shows this constructor:
template <class InputIterator> basic_regex(InputIterator first, InputIterator last, flag_type f = regex_constants::ECMAScript);
In 31.8.2 [re.regex.construct], p15, the constructor appears with this signature:
template <class ForwardIterator> basic_regex(ForwardIterator first, ForwardIterator last, flag_type f = regex_constants::ECMAScript);
ForwardIterator is probably correct, so the synopsis is wrong.

I think either could be implemented? Although an input iterator would probably require an internal copy of the string being made.
I have no strong feelings either way, although I think my original intent was InputIterator.
Adopt the proposed resolution in N2409.
