Milestone:  To Be Determined                        |   Component:  range     
  Version:  Boost 1.47.0                            |    Severity:  Problem   
 Keywords:  accumulate range const                  |  
----------------------------------------------------+-----------------------
 The first overload of boost::accumulate, (const SinglePassRange&, Value)
 is not checking for the proper concept. It checks for the non-const
 version, which causes problem when passing a range that is not mutable.

 The following line must changed from:
 BOOST_RANGE_CONCEPT_ASSERT(( SinglePassRangeConcept<SinglePassRange> ));

 To:
 BOOST_RANGE_CONCEPT_ASSERT(( SinglePassRangeConcept<const SinglePassRange>
 ));

 Like it is in the 2nd overload.
