Comment:

 I have run into the same problem when using the std::list constructor
 which only takes the list size.  Here is a test case:


 {{{
 #include <list>
 #include <boost/pool/pool_alloc.hpp>

 void foo()
 {
     typedef boost::fast_pool_allocator<int> Alloc;
     std::list<int, Alloc> myList(3);
 }
 }}}
 Compiled with GCC 4.6.1 using `-std=c++0x` and Boost 1.51.0, this results
 in the following errors:
 {{{

 I have changed the ticket type to "Bugs", since this version of Boost
 claims to support C++11 mode in GCC 4.6.
