10852,boost format operator % won't accept dereference of volatile,paul.d.rose@…,"James E. King, III","struct A{
    A() : a(9) {}
    int a;
};
A a;
A volatile *pva = &a;

  std::cout << boost::format(""%d"") % pva->a << std::endl;

This worked in 1_54 but fails in 1_56 with error:

format/feed_args.hpp:135:47: error: invalid conversion from 'volatile void*' to 'const void*'


Can work around this with cast:
  std::cout << boost::format(""%d"") % (int)pva->a << std::endl;    
but should not have to.  The appearance to the user is pass by value.

Running linux with g++ 4.6.2 and 4.8.2
