 Reporter:  anonymous         |      Owner:  timblechmann
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  heap
  Version:  Boost 1.58.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+--------------------------
 'boost::heap::pairing_heap<int, boost::heap::compare<Compare> >::end'
 tries to default-construct a 'Compare' object, and fails to compile if
 'Compare' is not default constructible.  This is an error.  If the
 iterator requires a 'Compare' object, it should copy-construct this from
 the object stored in the heap data structure.  See attached file for a
 minimal example
