10789	unexpected behaviour with boost range join on rvalue	Matei David <matei@…>	Neil Groves	"I'm trying to append one element to a range, and iterate over the resulting compound range. When the rhs of the `join` is an lvalue, everything seems ok. However, when the rhs of the `join` is an rvalue, I'm seeing something unexpected.

Specifically, when such a joined range is accessed directly by a `for(auto e : range)` loop, or when it is saved in a variable using `auto`, then iterated over, the singleton in the second container is not produced correctly. If however the joined range is passed by reference (other than non-const lvalue, obviously), then iterated over, the result is correct."	Bugs	new	To Be Determined	range	Boost 1.57.0	Problem
