12542	multi_index constraint violation if rollback callable is passed, but doesn't correct the issue	Jon Kalb <jonkalb@…>	Joaquín M López Muñoz	"If modify() is called taking two callables (the modifier and the rollback) in which the modifier changes a value one the element that results in the element not being acceptable (because a unique index would have a duplicate entry), then the rollback callable is called to correct the issue.

If the rollback callable does not correct the issue, the modification is committed anyway which leads to corruption of the unique index(es) involved."	Bugs	closed	To Be Determined	multi_index	Boost 1.61.0	Problem	fixed
