#2472: ptr_sequence_adapter<T>::sort fails to compile if T is an abstract base
class

     Type:  Bugs          |      Status:  new          
Milestone:  Boost 1.38.0  |   Component:  ptr_container
  Version:  Boost 1.36.0  |    Severity:  Problem      
 Keywords:                |  
--------------------------+-------------------------------------------------
 When calling ptr_vector<T>::sort, where T is an abstract base class I get
 the following compilation error, on MSVC++2008:


 {{{
 error C2027: use of undefined type 'boost::result_of<F>'
 1>        with
 1>        [
 1>            F=MyFunctorName(T,T)
 1>        ]
 }}}


 By making T a non-abstract base class (even though there should never be
 an element of type T in the container) the code compiles and runs as
 expected; therefore I believe I'm not missing any header files, nor is my
 compare functor faulted, so it might be a bug on the library.
