Comment (by pdimov):

 `unspecified_bool_type` is not a documented part of `shared_array` and is
 not present when explicit operators are supported. You should either use

 {{{
 #if !defined( BOOST_NO_CXX11_EXPLICIT_CONVERSION_OPERATORS )

     explicit operator bool () const
     {
         return m_data.size() > 0;
     }

 #else
     // your current definition
 #endif

 }}}

 or define your own `unspecified_bool_type`.

 Incidentally, your code above doesn't seem to compile, because
 `m_data.size() > 0` returns a `bool`, which is not convertible to
 `unspecified_bool_type`.
