Milestone:  To Be Determined                                        |   Component:  thread 
  Version:  Boost 1.52.0                                            |    Severity:  Problem
 Keywords:  allocator_destructor packaged_task temporary reference  |  
--------------------------------------------------------------------+-------
 The ctor of packaged_task creates a rebound allocator on the stack (stack
 frame of ctor). the allocator instance is passed to allocator_destructor
 which hold a '''reference''' to the allocator. Unfortunately the allocator
 instance will be destroyed/invalid after return from ctor.

 Suggestion, because of the allocators a required to by copyable
 allocator_destructor should store the value of the allocator instance
 (using allocators copy-ctor).
