Iterator range does not work with pointer to array as iterator

[Nathan Ridge]

The following code:

#include <boost/range/iterator_range.hpp>

template <typename T>
boost::iterator_range<const T*> one_element_range(const T& t)
{
    return boost::iterator_range<const T*>(&t, &t + 1);
}

int main()
{
    one_element_range("foo");
}

fails to compile with the following error:

In file included from test.cpp:1:
In file included from boost/range/iterator_range.hpp:13:
boost/range/iterator_range_core.hpp:349:12: error: function cannot return array type 'abstract_value_type' (aka 'char [4]')
           abstract_value_type operator()( difference_type at ) const
           ^
test2.cpp:11:5: note: in instantiation of template class 'boost::iterator_range<char const (*)[4]>' requested here
    one_element_range("foo");
    ^

I think this use case (pointer to an array as an iterator) should be supported.

patch + test

[Nathan Ridge]

(In [83596]) [range] allow iterator_range to be instantiated with a pointer to an array as the iterator type (refs #8338)

[Nathan Ridge]

Fixed in trunk.

(In [84823]) [range] Merge Boost.Range bug fixes to release branch (fixes #6944; fixes #7407; fixes #7408; fixes #7731; fixes #7827; fixes #8338; fixes #8453).

Fixed for 1.54.
