11802	Incorrect ordering after using insert() with ordered_range_t on a flat_multiset with a non-default sort order	mm-info@…	Ion Gaztañaga	"The attached file is a simple example. A set is created with the number 0 and two insertions are performed afterwards. The first one works, but the second one fails. The second one uses ordered_range_t.

This worked in earlier releases of Boost. I'm not sure when it failed to work, but I think I updated from 1.55 to 1.59.
