 I'm trying to use a offset_ptr<volatile int> to point to a piece of
 shared memory that can be changed by another process without other
 synchronization mechanisms.
 But I get this kind of errors:

 offset_ptr.hpp:116: error: invalid conversion from 'volatile void*'
         to 'const void*'
 offset_ptr.hpp:116: error: initializing argument 1 of 'void
         boost::interprocess::offset_ptr<T>::set_offset(const void*)
         [with PointedType = volatile int]'

 Basically it is not possible to call set_offset when the pointed type is
 volatile.
