#12542: multi_index constraint violation if rollback callable is passed, but
doesn't correct the issue

 Reporter:  Jon Kalb <jonkalb@…>  |      Owner:  joaquin
     Type:  Bugs                  |     Status:  new
Milestone:  To Be Determined      |  Component:  multi_index
  Version:  Boost 1.61.0          |   Severity:  Problem
 Keywords:                        |
----------------------------------+-------------------------
 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.
