3411,"Warnings when boost::exception is compiled with ""-Wold-style-cast""",c-rom (-at-) gmx.de,Emil Dotchevski,"Boost::exception reports warnings when compiled with ""-Wold-style-cast"".

Please see ticket #2983 which is very similar to this one.

The following code example reproduces the issue with Boost 1.40:

{{{
#include <iostream>
#include <boost/exception.hpp>

typedef boost::error_info<struct tag_my_info,int> my_info;

struct my_error: virtual boost::exception, virtual std::exception { };

void f()
{
  throw my_error() << my_info(42);
}

void g()
{
  try
  {
    f();
  }
  catch( my_error & x )
  {
    if( int const * mi=boost::get_error_info<my_info>(x) )
      std::cerr << ""My info: "" << *mi;
  }
}
}}}
