[string_algo] find_iterator broken in 1.53?

Reported by: gast128@… Owned by: Marshall Clow
Milestone: Boost 1.54.0 Component: string_algo
Version: Boost 1.53.0 Severity: Problem
Keywords: Cc:

Description

The find_iterator uses in its increment function the plus operator. This compiles for random access iterators but not for iterators with less capabilities, e.g.:

std::list<char> lst; std::vector<char> vec; std::string str;

ok boost::make_find_iterator(str, boost::first_finder(str));

ok boost::make_find_iterator(vec, boost::first_finder(str));

not ok boost::make_find_iterator(lst, boost::first_finder(str));

(In [82788]) Make find_iterator work with forward iterators; refs #7989

I was actually using the find_iterator on a file with a std::istream_iterator which is -I think- an input iterator. Those are ruled out then?

Milestone: To Be Determined → Boost 1.54.0

No they should work as well
