#7349: packaged_task holds refence to temporary
--------------------------------------------------------------------+-------
 Reporter: olli | Owner: viboes
     Type: Bugs | Status: new
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).
