range_detail::make_range() copies containers needlessly

Reported by: Michael Burr <michael.burr@…> Owned by: Neil Groves
Milestone: To Be Determined Component: range
Version: Boost 1.48.0 Severity: Problem
Keywords: Cc:

Description

When manufacturing a range for the passed in containers, range_detail::make_range() calls range_detail::is_char_ptr() which will takes its (unused) parameter by value just so 0L can be returned.

This means make_range() can't be used with non-copyable classes.

See ​http://stackoverflow.com/questions/8571608/why-does-boostequals-require-ranges-to-be-copyable for the original report of this problem by Mozza314.
